It's not just poetic flourish. According to Devarim Rabbah, there's a profound and multifaceted reason why Moses calls upon them as witnesses, as partners, as something more.
Rabbi Yehoshua of Sikhnin, in a fascinating interpretation, suggests that the heavens themselves possess a mouth, a heart, and an ear! A mouth? Absolutely, because "The heavens relate the glory of the Almighty" (Psalms 19:2). A heart? Undeniably, because "The mountain was burning with fire to the heart of the heavens" (Deuteronomy 4:11). And an ear? Well, that's where our verse comes in: "Listen, heavens..." (Deuteronomy 4:1). It's a powerful image, isn't it? The heavens as a sentient being, capable of hearing, feeling, and speaking.
But why both the heavens and the earth? Rabbi Shmuel bar Naḥman offers a compelling parable. Imagine a governor serving two provinces, one taxed and one tax-exempt. If he throws a feast for one, the other will be resentful. So, he invites both. Similarly, Moses, who achieved greatness both on earth and in the heavens ("He was there with the Lord forty days..." - (Exodus 34:2)8), invites both as witnesses. He doesn't want to slight either realm.
There's more. Rabbi Tanḥuma points out that God redeems Israel through the heavens and the earth. "Sing, the heavens, as the Lord has acted; shout, depths of the earth…for the Lord has redeemed Jacob, and in Israel He is glorified" (Isaiah 44:23). The Torah itself, according to Devarim Rabbah, was given through them: "From the heavens, He had you hear His voice…and upon earth He showed you His great fire" (Deuteronomy 4:36). And remember the manna and the quail in the desert? They came from the heavens and the earth (Exodus 16:4, 16:13).
The heavens and the earth also reflect God's promise to Israel. He compared them to the stars of the heavens and the dust of the earth, symbols of countless progeny (Genesis 15:5, 28:14). They are, essentially, the ultimate witnesses to the covenant between God and Israel.
Think of it like this: a king gives his son two stewards, and every coronation is done through them. When the son marries, he takes these stewards as witnesses between himself and his father. Similarly, all the miracles God performed for Israel were done through the heavens and the earth.
Rabbi Ḥanina offers another perspective. Imagine someone who leaves a deposit with a friend, but the friend dies. The depositor's son treats both the friend's son and his wife with deference, unsure with whom the deposit truly lies. Likewise, Moses, knowing his death is near and uncertain where his soul will go ("Who knows the spirit of the sons of man? Does it ascend upward...?" - (Ecclesiastes 3:2)1), commands both the heavens and the earth, hoping his soul will find a good place.
The story goes that God reassures Moses that his soul will be safe, bound beneath the Throne of Glory, as Avigayil says, "May the soul of my lord be bound in the bond of life with the Lord your God" (I (Samuel 25:2)9).
Finally, and perhaps most poignantly, the heavens and the earth are witnesses to Israel's entire journey: their sins, their suffering, and their eventual consolation. They witnessed the idolatry, like making "pastries in honor of the queen of the heavens" (Jeremiah 7:18). They witnessed the destruction, when "the heavens, and their light is gone" and the land became "emptiness and disorder" (Jeremiah 4:23). But they will also witness the ultimate redemption, when "the new heavens and the new earth…will remain before Me…so your descendants and your name will remain" (Isaiah 66:22).
So, the next time you hear the phrases "heavens and earth" together, remember it's more than just a figure of speech. It's a connection to something ancient, powerful, and deeply meaningful about our relationship with God and the world around us. It's a reminder that everything is interconnected, and that even the cosmos itself is a witness to our story.
Another matter, “listen, heavens” – Rabbi Yehoshua of Sikhnin said: From here you derive that the heavens have a mouth, a heart, and an ear. A mouth, from where is it derived? It is as it is written: “The heavens relate the glory of the Almighty” (Psalms 19:2). A heart, from where is it derived? It is as it is written: “The mountain was burning with fire to the heart of the heavens” (Deuteronomy 4:11). An ear, from where is it derived? It is as it is written: “Listen.” Another matter, why to the heavens and the earth?5Why did Moses address the heavens and the earth in this verse? Rabbi Shmuel bar Naḥman said: To what is the matter comparable? It is to a military governor who served in two provinces, one subject to taxation and one tax-exempt. He made a festival. He said: ‘If I invite these, those will be angry, and if I invite those, these will be angry.’ What did he do? He invited these and those. So, Moses was from the earth and achieved greatness in the heavens. From where is it derived? It is as it is stated: “He was there with the Lord forty days…” (Exodus 34:28). He said: ‘If I invite the heavens, the earth will be angry, and if I invite the earth, the heavens will be angry.’ He said: ‘I will invite both of them, the heavens and the earth,’ as it is stated: “Listen, heavens…[and the earth will hear].” Another matter, why to the heavens and the earth? Rabbi Tanḥuma said: It is because the Holy One blessed be He redeems Israel only by their means,6By means of the heavens and the earth. as so it is written: “Sing, the heavens, as the Lord has acted; [shout, depths of the earth…for the Lord has redeemed Jacob, and in Israel He is glorified]” (Isaiah 44:23). Another matter, why to the heavens and to the earth? It is because the Torah was given only through them, as it is stated: “From the heavens, He had you hear His voice to chastise you, and upon earth He showed you His great fire [and you heard His words from the midst of the fire]” (Deuteronomy 4:36). Another matter, it is because the manna and the quail came through them. From where is it derived? It is as it is stated: “Behold, I am raining food for you from the heavens” (Exodus 16:4), and the quail from the earth, as it is written: “The quails came up…” (Exodus 16:13). Another matter, it is because the Holy One blessed be He analogized Israel to the stars of the heavens and to the dust of the earth. Like the stars of the heavens, from where is it derived? It is as it is written: “Look to the heavens and count the stars…” (Genesis 15:5). Like the dust of the earth, from where is it derived? “Your offspring will be like the dust of the earth” (Genesis 28:14). Another matter, why to the heavens and to the earth? It is because they are Israel’s witnesses, as it is written: “I call today to the heavens and earth to bear witness against you” (Deuteronomy 4:26). To what is the matter comparable? It is to the son of kings, to whom his father gave two stewards, and every crown with which his father would crown him, he would crown him only through them. When he entered his wedding canopy, he took them as witnesses to be intermediaries between him and his father, So, all the miracles that the Holy One blessed be He performed on behalf of Israel, he performed it for them by means of the heavens and the earth. When they came to enter the Land of Israel, they recited song through them, as they testify between Him and them. From where is it derived? It is as it is stated: “Hear, heavens and listen, earth, as the Lord has spoken” (Isaiah 1:2). What is written thereafter? “I have reared children and exalted them [and they rebelled against me]” (Isaiah 1:2). That is, “listen, heavens.” Another matter, why to the heavens and to the earth? Rabbi Ḥanina said: To what is the matter comparable? It is to one who deposited a deposit with his friend. The friend, who deposited the deposit with him, died, and the son of the one who deposited the deposit arose and treated the one with whom he had deposited the deposit with deference and treated his wife with deference. They said to him: ‘Why are you treating both of them with deference?’ He said to them: ‘I have a deposit with them, but it is unclear to me with whom the deposit is, whether it is with him or with his wife; [I treat them both with deference] so that wherever my deposit is placed, it will be well guarded.’ So, they said to Moses: ‘Why are you commanding the heavens and the earth?’ He said to them: ‘I am destined to die, and I do not know where my soul is going, whether to the heavens or to the earth.’ From where is it derived? It is as it is stated: “Who knows the spirit of the sons of man? Does it ascend upward, [and the spirit of the animal, does it descend downward to the earth?]” (Ecclesiastes 3:21). That is why I am commanding both of them. Everywhere that my soul will be placed, it will be good. The Holy One blessed be He said to him: ‘As you live, no creature has dominion over your soul. Where is it placed? It is beneath the Throne of Glory.’ As so says Avigayil: “May the soul of my lord be bound in the bond of life with the Lord your God” (I Samuel 25:29). Another matter, why to the heavens and to the earth? It is because through them, the Holy One blessed be He bore witness against Israel; through them, they sinned; through them, they were stricken; and through them, they are consoled. Through them He bore witness against them, from where is it derived? It is as it is written: “I call today to the heavens and the earth to bear witness against you” (Deuteronomy 4:26). Through them they sinned, as it is written: “To make pastries in honor of the queen of the heavens”7This refers to idol worship. (Jeremiah 7:18). Through them they were stricken, from where is it derived? It is as is written: “And the heavens, and their light is gone” (Jeremiah 4:23). Through the earth, from where is it derived? It is as it is written: “[I call the heavens] and the earth [to witness against you that you shall soon perish from the land…]” (Deuteronomy 4:26). Through the earth they sinned, from where is it derived? It is as it is written: “Their altars too will be as heaps on the furrows of the field” (Hosea 12:12). Through the earth they were stricken, as it is written: “I saw the land, and behold, it is emptiness and disorder” (Jeremiah 4:23). And through the heavens and the earth they are consoled, as it is written: “For just as the new heavens and the new earth [that I will make will remain before Me, the utterance of the Lord, so your descendants and your name will remain]” (Isaiah 66:22).
