What made Eli the priest live so long? The midrash gives a simple answer: Torah study. "Fortunate is the man who listens to me, watching daily at my gates, waiting at the posts of my doors" (Proverbs 8:34). Eli was sitting at the doorpost of the Temple when Hannah came to pray (1 Samuel 1:9). The verse uses "sitting" not as a passive description but as a spiritual posture — the man who has stationed himself at the gate of wisdom and refuses to leave.
But the same passage asks the harder question. Eli's sons, Hophni and Phinehas, were corrupt — they stole from the offerings and slept with the women who served at the entrance of the Tent of Meeting. Eli knew. He rebuked them, mildly, and then did nothing. The midrash is harsh: "He who sins against me wrongs his own soul" (Proverbs 8:36) applies to Eli's sons directly. But it also reaches backward to Eli — a father who taught Torah all his life and failed to enforce it in his own house.
The contrast between Eli's long life and his catastrophic end — the ark captured, his sons killed in one day, Eli himself dying when he heard the news — is the midrash's way of saying that Torah study alone is not enough. Knowledge without action curdles. Eli sat at the gate of wisdom for ninety-eight years. He never got up to stop his sons. God gave him long life and then demonstrated that length of days is not the same thing as a life well-lived.
Chapter 40: Torah [1] And it came to pass, that when Isaac was old (Genesis 27:1). Twenty generations passed until Abraham, in which old age is not mentioned except for him, as it says, "Now Abraham was old" (Genesis 24:1). And Isaac also stood [before God] and it came to pass, that when Isaac was old (Genesis 27:1). And Jacob also stood [before God], as it says, "And the eyes of Israel were dim with age" (Genesis 48:10). The verse (Psalms 102:17) says, "He will regard the prayer of the destitute, and not despise their prayer." The only way [to achieve this level of prayer] is through old age, as it says, "The beauty of young men is their strength, and the glory of old men is their gray hair" (Proverbs 20:29). Abraham merited his son through five things, as our Rabbis taught: the father merits a son through five things: through his [the father's] name, through his [the father's] good deeds, through his [the father's] wealth, through his [the father's] strength, and through his [the father's] wisdom. Similarly, Isaac [merited his son through five things], and similarly Jacob [merited his son through five things]. Similarly, Jacob merited Joseph [through these five things], who resembled him in appearance and in title, as it says, "And Joseph was handsome in form and appearance" (Genesis 39:6). [He resembled him] in wisdom, as it says, "Behold, he is the master of dreams" (Genesis 37:19). He had beauty, appearance, and wisdom. And in Isaac's case, it is written, "Who is this man?" (Genesis 24:65). What is the meaning of "this man" in reference to Joseph? That he was handsome and had wisdom. Likewise, Isaac was also built with wisdom. And just as Joseph stood up to his brothers in strength, so did Isaac stand up in strength against all the men of Gerar. Just as Joseph was wealthy, so was Isaac wealthy, as it says, "And the man became great and went forward and became very great" (Genesis 26:13). The verse (Genesis 26:8) explains [the word] "wisdom" as meaning "the greatness of his children." From where do we learn that Isaac was handsome like Joseph? It is written about Joseph, "And Joseph was handsome in form and appearance," and when he went to his brothers, what did they say? "Behold, the master of dreams is coming!" (Genesis 37:19). And it is said about Isaac, "Who is this man?" (Genesis 24:65). What is the meaning of "this man" in reference to Joseph? That he was handsome and had wisdom. Likewise, Isaac was also built with strength, as it says, We know this from the fact that he dug many wells, as it says, "Isaac dug again the wells of water" (Genesis 26:18), and "Isaac's servants dug in the valley" (Genesis 26:19), and "they dug another well" (Genesis 26:21). He had strength in his hands. From where do we know that he was wealthy? It says, "The man became great, and he grew richer and richer until he was very wealthy" (Genesis 26:13). And from where do we know that he lived to a ripe old age of 180 years? It says, "And Isaac lived one hundred and eighty years" (Genesis 35:28). Abraham was the son of Terah, and Isaac was the son of Abraham. Why does the Torah mention this? Because God said to Isaac, "You have merited these five things, so I will add another five years to your life, like your father Abraham." That is why it says, "Look upon your servants" (Psalms 119:16). Anyone who has merit will receive these five things, and anyone who does not have merit will receive five calamities in return. And who was this? Joab, as it is said: "Let Joab and his descendants be perpetually guilty of their bloodshed. May they be afflicted with leprosy, jaundice, and starvation." (2 Samuel 3:29) Leprosy corresponds to strength; one who has leprosy has no strength. Jaundice corresponds to beauty; even if someone is young and jaundiced, there is no beauty in them. Starvation corresponds to wealth, as it says, "Come, eat my food and drink the wine I have mixed. Leave your simple ways and you will live" (Proverbs 9:5-6). One who is starving has no leisure to engage in Torah study. Falling by the sword corresponds to the five aspects of praise. These are five calamities corresponding to five aspects of praise. One who does not merit praise inherits these five kinds of calamities, like Joab. But one who does merit praise receives them like Isaac, as it is said, "And it came to pass, when Isaac was old" (Genesis 27:1), and David cries out, "May your children be like your ancestors" (Psalms 45:17). Therefore, it says, "And it came to pass, when Isaac was old." [2] Another interpretation: "And it came to pass when Isaac was old." This teaches that "You have done many things, O Lord my God, even Your wonderful works and Your thoughts towards us" (Psalms 40:6). Israel said to Him, "You have done many wonders and thoughts for us. Why do You do all these wonders for us? Why do You think these thoughts for us?" As it is said, "Your wonders and Your thoughts towards us." For us, You punished the wicked and You punished the righteous. How did God know that Isaac loved Esau and was about to bless him? God said, "I will dim Isaac's eyesight so that he will not see who he is blessing, so that Jacob will receive the blessings." Therefore it is written, "And it came to pass when Isaac was old." [3] Another interpretation: when Isaac grew old, it is written above that "Esau was forty years old, and he took as wives Judith the daughter of Beeri the Hittite, and Basemath the daughter of Elon the Hittite, and they made life bitter for Isaac and Rebekah." (Genesis 26:34-35). "A foolish son is a vexation to his father, and bitterness to her that bore him." (Proverbs 17:25). Yet, despite all of this, his father called him "the elder." "And Isaac called Esau his elder son" (Genesis 27:1), and his mother called him "the elder," as it says, "And Rebekah took the goodly garments of her elder son Esau" (Genesis 27:15). The Holy One, blessed be He, said, "Behold, there are the old and the aged who lack understanding, but I called him 'small,' as it is said, 'Behold, I have made you small among the nations'" (Obadiah 1:2). This is similar to a person who had a text to write that said, "heroic knights." Someone came to him to have his son's name inscribed and said to him, "Look at my son. He is young, but tall and sturdy." His mother also said, "Look at our son. He is tall and sturdy." He replied to them, "He is tall and sturdy before you, but I do not know. After all, the scale (i.e., measuring tool) will determine his true height. If he is indeed tall, then he will be measured and found to be tall. However, if he is not tall, then he will be measured and found to be small and disqualified." Thus, Rebekah called him "the elder," and Isaac called him "the elder." The Holy One, blessed be He, said to them, "Who else in My world is sovereign and rules without Me? As it is said, 'Who is he that speaks, and it comes to pass, unless the Lord commands it?' (Lamentations 3:37). He said to them, "Why do you insist on calling him 'the elder' in My house? I made him small." And you call him 'the elder,' but he is only small, as it is said, 'Behold, I have made you small among the nations'" (Obadiah 1:2).
