Believe it or not, our ancient texts have something profound to say about it.
The Bamidbar Rabbah, a collection of Midrashic (rabbinic interpretive commentary) teachings on the Book of Numbers, dives deep into this very issue. Specifically, it connects the idea of inheriting the land of Israel with… sexual morality. Seems like a leap. But let's unpack it.
It starts with the verse, "Ish ish" – "each man" – from (Genesis 17:8): “I will give to you and to your descendants after you, the land of your residence.” The Midrash sees a connection between this promise to Abraham and the verse in (Deuteronomy 23:15): “As the Lord your God walks [in the midst of your camp].” What's the link? Well, Bamidbar Rabbah is telling us that God's presence, and therefore the fulfillment of His promise, is contingent on the holiness of the community.
Think of (Proverbs 5:7-10), which warns, "Now, children, listen to me.… Distance your way from her.… lest you give [your glory] to others.… lest strangers be sated with your strength.” Who are these "children?" The Midrash tells us this is addressed to all of Israel, whom (Deuteronomy 14:1) calls “children to the Lord your God.” The warning is about straying from the path of mitzvot, the commandments, and in this context, specifically about avoiding illicit relationships.
Why this focus on adultery? The text pulls no punches. It claims that the exile of the ten tribes, and later Judah and Benjamin, was a direct result of widespread sexual immorality. They "sullied their beds with semen that was not theirs," as (Amos 6:4) describes. They swapped wives! This wasn't just a personal failing; it was a societal breakdown. As we find in II (Kings 18:11-12), they were exiled because "they did not heed the voice of the Lord…and they did not heed and did not perform."
The consequences were dire. (Proverbs 5:9) warns, “Lest you give your glory [hodekha] to others.” Hodekha, the Midrash explains, refers to the kingdom itself! They lost their kingdom, their strength, their very land. Foreigners came in and "were sated with your strength,” as (Proverbs 5:10) puts it. This "strength," according to (Genesis 4:12), is the fertility and bounty of the land itself!
And it gets even more intense. The "toils" (vaatzavekha) mentioned in (Proverbs 5:10) are interpreted as children! As (Genesis 3:16) says, “In pain [be’etzev] you shall bear children.” Adultery leads to children of uncertain lineage, mamzerim, who are excluded from the community. (Micah 2:9) laments that these adulterous acts banish women from their homes and rob children of their true heritage. They are a "defiled inheritance," as (Micah 2:10) states, a "rope [ḥevel] nimratz" – a severed connection to the past.
The Midrash even uses a clever notarikon, an acronym, to define nimratz: noef (adulterer), mamzer (illegitimate child), rasha (wicked one), tzorer (oppressor). It’s a stark warning about the cascading consequences of sexual sin.
But why is lineage so crucial? Rabbi Shmuel bar Naḥman, quoting Rabbi Yonatan, points out that even in war, the purity of lineage matters! The descendants of Asher, mentioned in I (Chronicles 7:40), benefited from the "merit of their lineage" in battle. (Deuteronomy 23:2-4) forbids those with "crushed testicles" and mamzerim from entering the assembly, emphasizing the importance of purity within the community.
Moses, in (Deuteronomy 23:15), tells the Israelites that God only associates His name with them when their "camp shall be holy." This holiness, according to (Leviticus 20:7-8), is directly tied to observing God's statutes, specifically the laws against forbidden relationships.
The text even delves into some seemingly strange juxtapositions in the Torah. Why is cursing one's parents mentioned between sanctification and adultery in Leviticus 20? The answer, the Midrash suggests, is that adultery can lead to children who don't know their true parents and therefore curse them.
Ultimately, the Bamidbar Rabbah is arguing that a society's moral fabric is inextricably linked to its destiny. God promised the land to Abraham and his descendants, but that promise is conditional. It depends on maintaining a society where lineage is clear, where families are strong, and where sexual morality is upheld.
It’s a challenging message, isn't it? It asks us to consider the long-term consequences of our choices, not just on ourselves, but on future generations. It forces us to confront uncomfortable truths about the relationship between personal behavior and collective destiny. Can a society truly thrive if its foundations are built on shaky moral ground? That's the question this ancient text leaves us to ponder.
Another matter: “Ish ish” – that is what is written: “I will give to you and to your descendants after you, the land of your residence…” (Genesis 17:8). “I will give to you” (Genesis 17:8) – that is what is written: “As the Lord your God walks [in the midst of your camp]” (Deuteronomy 23:15). That is what is written: “Now, children, listen to me.… Distance your way from her.… lest you give [your glory] to others.… lest strangers be sated with your strength” (Proverbs 5:7–10). What is, “Now, children, listen to me”? It is speaking of the ten tribes and the tribe of Judah and Benjamin, as all Israel are called children, as it is stated: “You are children to the Lord your God…” (Deuteronomy 14:1). “Listen to me” – he cautioned them to fulfill the obligation to heed. “Do not depart from the sayings of my mouth.” (Proverbs 5:7) – he cautioned them to fulfill the performance [of mitzvot] as they accepted upon themselves at Sinai. “Everything the Lord has spoken we will perform and we will heed” (Exodus 24:7) – it was for the transgression of both of them that they were exiled, as it is stated: “The king of Assyria exiled Israel.… because they did not heed the voice of the Lord…and they did not heed and did not perform” (II Kings 18:11–12). “Distance your way from her” (Proverbs 5:8) – he cautioned them to distance harlotry from them. “And do not approach the entrance of her house” (Proverbs 5:8) – he cautioned them regarding forbidden relations, in whose regard it is stated: “Any man of you shall not approach his kin to uncover nakedness” (Leviticus 18:6). “Lest you give your glory [hodekha] to others” (Proverbs 5:9) – they will lose their kingdom, and it will be exalted for the nations. Hodekha is nothing other than kingdom, just as it says: “Upon whom the glory [hod] of kingdom was not placed” (Daniel 11:21). “And your years to the cruel” (Proverbs 5:9) – they gave their years to a cruel angel, as their days and years drew near to being eliminated, just as it says: “You brought your days near and came to the end of your years…” (Ezekiel 22:4). “Lest strangers be sated with your strength” (Proverbs 5:10) – they were exiled from their land, and foreigners settled in their place and consumed their strength and exertion. “Your strength” is nothing other than the strength of their land, as it is stated: “When you work the ground [it will no longer give its strength to you]” (Genesis 4:12). Likewise you find that when the king of Assyria exiled the ten tribes, he settled foreigners in their land, as it is stated: “The king of Assyria brought from Babylon, from Kuta, from Ava, and from Ḥamat, [and Sefarvayim, and he settled them in the cities of Samaria in place of the children of Israel” (II Kings 17:24). That is, “lest strangers be sated with your strength.” “And your toils [vaatzavekha] be in the house of a stranger” (Proverbs 5:10) – toils [atziva] are nothing other than children, just as it says: “In pain [be’etzev] you shall bear children” (Genesis 3:16). Another matter: “Vaatzavekha” (Genesis 3:16) – this is toil of the land, saying that they will eat with toil everything that they eat in the foreign land, just as it says: “With toil [be’itzavon] you shall eat of it…” (Genesis 3:17). And likewise it says: “The king of Assyria exiled Israel to Assyria…” (II Kings 18:11). All this befell the ten tribes because they were steeped in harlotry with married woman. It was over that that their sentence was sealed, as it is stated in their regard: “Who lie on beds of ivory, and sprawl [usruḥim] on their couches…” (Amos 6:4); they would sully their beds with semen that was not theirs, as they would swap their wives with one another. What is written thereafter? “Therefore, now they will be exiled at the head of the exiles, and the revelry of the sprawled [seruḥim] will be discontinued” (Amos 6:7). At that time the rejoicing of the seruḥim will be removed. Likewise, Micah prophesied in their regard: “The women of My people you banish [tegareshun] from the house of her delight; from their young children, you take My grandeur forever” (Micah 2:9). The verse relates that they would violate men’s wives and render them forbidden to their husbands, and they would divorce [megareshin] them. That is, “the women of My people you banish [tegareshun] from the house of her delight”; this is the house of her husband, in which she would delight. What is, “from their young children, you take My grandeur forever”? The only grandeur I had in this world was from the young children, as it is stated: “From the mouths of young children and suckling babes You founded strength” (Psalms 8:3). And I am glorified through them, just as it says: “In the multitude of people is the glory of a king” (Proverbs 14:28). But you have rendered them mamzerim; you have voided that glory of mine, as I do not want mamzerim, as it is written: “A mamzer11A mamzer is a child born of a forbidden union punishable by karet, e.g., between a married woman and a man other than her husband. shall not enter the congregation of the Lord…” (Deuteronomy 23:3). What is written thereafter? “Arise and go, as this is not the resting place; because it was defiled it will destroy you, and it will be an intense destruction [veḥevel nimratz]” (Micah 2:10). The Holy One blessed be He said to them: For the rest of the transgressions I would have shown you forbearance. Because you have spread to adultery, “arise and go….” What is “veḥevel nimratz”? I said: “For the portion of the Lord is His people, Jacob the allotment [ḥevel] of His inheritance” (Deuteronomy 32:9). I took Jacob as My inheritance. He was My portion, because his descendants were all similar to a rope [ḥevel], which is intertwined one with another, as the descent of all of them was traceable to their ancestors, There was no offspring that was not theirs that interrupted between them, as they guarded themselves from adultery and there was no mamzerut there. How so? It is written: “Elazar begot Pinḥas, Pinḥas begot Avishua” (I Chronicles 5:30), and the same is true for all of them. The lineage continued in that manner. But you entered with the wife of another and defiled the inheritance. How can he enumerate: So-and-so, my son, and he is not his son, as he is a mamzer; you severed the rope. That is ḥevel nimratz. What is nimratz? Adulterer [noef], mamzer, wicked one [rasha], oppressor [tzorer].12Nimratz is spelled with the first letters of noef, mamzer, rasha, tzorer. You learned that regarding the ten tribes, their sentence was sealed only due to the iniquity of adultery. From where is it derived that regarding the tribe of Judah and Benjamin, their sentence was sealed only due to the iniquity of adultery? It is as Jeremiah screams before God: ‘During the days of Menashe, Israel performed wickedness greater than them [of my generation], but You did not destroy them, but rather in my days.’ That is what is written: “My innards, my innards, I shudder, the walls of my heart, [my heart sighs to me]” (Jeremiah 4:19). The Holy One blessed be He said to him: During the days of Menashe, even though they angered Me, the children were the children of their fathers. Now they are the children of lewdness. That is what is written: “For My people are foolish…” (Jeremiah 4:22). What is written at the end of the passage? “They were lustful horses rising early; each would neigh to his neighbor’s wife” (Jeremiah 5:8). Even though they transgressed all the mitzvot and denied the Holy One blessed be He, just as it is stated: “They denied the Lord” (Jeremiah 5:12), He displays forbearance. It is only for the adultery that their sentence was sealed, as, indeed, it is written thereafter: “Will I not reckon for these, the utterance of the Lord…” (Jeremiah 5:9). The Holy One blessed be He said: For everything I will restrain myself, but for lewdness I am angry. I will deliver them to the kingdoms. That is what is written thereafter: “Enter within its walls…” (Jeremiah 5:10). “Lest strangers be sated with your strength” (Proverbs 5:10). Likewise Moses said to Israel: When you go out to war, be careful that there will not be among you the iniquity of adultery, as if there is the iniquity of lewdness in your midst, the Holy One blessed be He, who wages war on your behalf, will turn away from you, and you will be delivered into the hand of your enemies. That is what is written: “For the Lord your God walks [in the midst of your camp to deliver you and to deliver your enemies before you and your camp shall be holy], and He shall not see a shameful matter among you and turn away from you” (Deuteronomy 23:15). What is, “for the Lord your God”? Moses said to Israel: Know that the Holy One blessed be He associates His name with Israel, as He is called, “your God,” only when “your camp shall be holy.” At that time, He rests His Divine Presence in your midst, and He rescues you from the hands of your enemies and delivers your enemies to you. That is what is written: “Walks in the midst of your camp to deliver you…” From where is it derived that Israel is called holy when they protect themselves from adultery and lewdness? It is as it is written: “You shall sanctify yourselves, and you shall be holy, as I am the Lord your God” (Leviticus 20:7). From here, when they are holy, He is God to them. What is written thereafter? “You shall observe My statutes, and perform them; I am the Lord who sanctifies you” (Leviticus 20:8). When does the Holy One blessed be He sanctify Israel? It is when they observe His statutes. What are the statutes? These are the forbidden relations, as adultery with a married woman is written first, as it is stated: “A man who will commit adultery [with a married woman]” (Leviticus 20:10). What did it see that led it to have cursing one’s father or mother interpose between sanctification and adultery? It is because initially it is written: “For each man who shall curse his father” (Leviticus 20:9). What causes the son to curse his father? It is adultery. It is because he believes that his mother’s husband is his father and he honors him, and he believes that the adulterer is not his father and he curses him. Similarly, you say: “One who strikes his father or his mother.… One who abducts a man and sells him.[… One who curses his father or his mother…]” (Exodus 21:15–17). What did it see that led it to have one who abducts a person interpose between one who strikes and one who curses? Would it not have been appropriate not to interpose between them, as both are stated regarding a punishment generated by his father and his mother? Why did it do so? It is to teach you that it is for this that one who abducts an Israelite person incurs liability, because he [the person abducted] strikes his father and his mother and curses them because he did not grow up with them and does not know them. Here too, this is why cursing one’s father interposes between sanctification and harlotry. It is because anyone who consorts with one of the forbidden relations stated in the Torah, at times he begets a son and causes the mamzer to curse his father. Why does it mention the cursing of the mother; does he not recognize his mother? When does he recognize his mother? When the mamzer is from adultery with a married woman, as the adulteress attributes him to her husband. However, regarding all other unmarried forbidden relations, they cast their child in the streets due to the shame, and others raise them. Those mamzerim recognize neither their father nor their mother. Even a mamzer from a married woman occasionally recognizes neither his father nor his mother. When? It is when she committed adultery while her husband was in lands overseas and she casts him away. That is why the Torah punishes one who consorts with a married woman or with forbidden relations with court-imposed execution and karet. That is why it is stated: “And your camp shall be holy” (Deuteronomy 23:15). Another matter: “And your camp shall be holy” (Deuteronomy 23:15) – we learned there: One need not investigate from the altar13Priests and beyond, from the platform14Levites and beyond, nor from the Sanhedrin and beyond. Anyone whose ancestors were public officials or charity collectors may marry into the priesthood, and there is no need to investigate them. Rabbi Yosei says: The same is true of one who had signed as a witness in the old court of Tzippori. Rabbi Ḥanina ben Antigonus says: The same is true of one who was written in the army roster of a Jewish king.15Kiddushin 76a. The midrash is stating that one can rely on all these individuals’ presumptive status of unflawed lineage. It is written: “You shall place a king over you…” (Deuteronomy 17:15). I have derived only a king of Israel; from where is it derived to include public officials, charity collectors, judges’ scribes, and floggers with the strap? The verse states: “From among your brethren you shall place a king over you” (Deuteronomy 17:15) – anyone whom you place over you, shall be only from among your brethren, from the select of your brethren. Rabbi Shmuel bar Naḥman says in the name of Rabbi Yonatan: From where is it derived that those going out to war need that no mamzerim be in their midst? It is as it is written regarding the descendants of Asher: “Their lineage for military service” (I Chronicles 7:40) – the merit of their lineage stands for them in war. To this point it is from the texts of tradition;16Prophets and Writings. from the words of the Torah, from where is it derived? It is as it is written: “One with crushed […testicles]…shall not enter [into the assembly of the Lord]. A mamzer shall not enter.… An Amonite shall not enter.… Do not despise an Edomite.… [Sons born to them of the third generation may enter…]” (Deuteronomy 23:2–4, 8–9). What is written thereafter? “When a camp shall go out against your enemy” (Deuteronomy 23:10); that is why it is written: “And your camp shall be holy…” (Deuteronomy 23:15), that there shall not be in their midst mamzerim and not those who are born not in sanctity, because the Holy One blessed be He does not associate His name with them and does not aid them in war. So, the Holy One blessed be He said to Abraham our patriarch: “I will give to you and to your descendants after you the land of your residence” (Genesis 17:8) – to those descendants whose descent will be traced back to you, I will give them “the land of your residence…as an eternal possession” (Genesis 17:8), and I will be their God. But mamzerim, whose descent is not traced back to you, as their forebears are not distinguishable, I will not be their God, as I do not associate My name with them and I will not give them a portion in the land.
