Rabbi Avin began in the name of Rabbi Berekhya the Elder: “You then spoke in a vision to Your pious ones, [saying: I aided the mighty one; I raised the one chosen from the people]” (Psalms 89:20) – this is speaking of Abraham, to whom He spoke with speech and in vision. That is what is written: “After these matters, the word of the Lord came to Abram in a vision, saying” (Genesis 15:1). “To Your pious ones [laḥasidekha]” – “give truth to Jacob, kindness [ḥesed] to Abraham” (Micah 7:20).
“Saying: I aided the mighty one” – as he killed four kings in one night. That is what is written: “He deployed against them at night…[and smote them and pursued them until Ḥova]” (Genesis 14:15). Rabbi Yitzḥak said: Do you have a person who pursues the dead, as it is stated: “And smote them and pursued them until Ḥova”? Rather, it teaches that the Holy One blessed be He was killing and Abraham was pursuing.
“I raised the one chosen from the people” – this is Abraham, who was chosen by the Holy One blessed be He, as it is stated: “Who has chosen Abram” (Nehemiah 9:7). Another matter: “You then spoke in a vision to Your pious ones” (Psalms 89:20) – this is speaking of David, to whom He spoke with speech and in vision. That is what is written: “In accordance with all these matters, and in accordance with this entire vision, so Natan spoke to David” (II Samuel 7:17).
“To Your pious ones [laḥasidekha]” – as it is stated: “Protect my soul, for I am pious [ḥasid]” (Psalms 86:2). “Saying: I aided the mighty one” (Psalms 89:20) – Rabbi Abba bar Kahana said: David waged thirteen wars, and the Rabbis say: Eighteen, and they do not disagree. The one who said thirteen, they were for the needs of Israel. The one who said eighteen, they were five for his own needs and thirteen for the needs of Israel.
“I raised the one chosen from the people” (Psalms 89:20) – as it is stated: “He chose David His servant…” (Psalms 78:70). Another matter: “You then spoke in a vision” (Psalms 89:20) – this is speaking of Moses, to whom He spoke with speech and in vision, as it is stated: “Mouth to mouth I will speak to him, [and a vision]” (Numbers 12:8). “To Your pious ones” (Psalms 89:20) – because he was from the tribe of Levi, as it is stated: “Your Tummim and Your Urim for Your pious one” (Deuteronomy 33:8).
“Saying: I aided the mighty one” (Psalms 89:20) – this accords with that which Rabbi Tanḥum bar Ḥanilai said: The way of the world is that a burden that is difficult for one is easy for two; [one that is difficult] for two is easy for four. But can a burden that is difficult for six hundred thousand be easy for one? All of Israel was standing before Mount Sinai and saying: “If we continue to hear [the voice of the Lord our God any more, we will die]” (Deuteronomy 5:22), and Moses was hearing the voice of the divine speech himself, and he lived.
Know that it is so, as from all of them, the divine speech called only to Moses, as it is stated: “He called to Moses.” “I raised the one chosen from the people” (Psalms 89:20) – as it is stated: “Were it not for Moses His chosen one” (Psalms 106:23).
