מדרש אויף תהילים 82:5

(Fol. 55) We are taught: What songs did the Levites chant on the intermediate days (Chol Hamoed)? The songs were as follows: On the first day they said (Ps. 29) Ascribe unto the Lord, O ye sons of the mighty; on the second, (Ps. 50); on the third, (Ps. 94); on the fourth, (Ib. 8); on the fifth day, (Ib. 81); on the sixth day they said (Ps. 82) All the foundations of the earth are moved. If the Sabbath falls on one of these days, the song, all the foundations of the earth are moved, [the last one] should be superseded.

(Gen. 20:1:) THEN ABRAHAM JOURNEYED FROM THERE. This text is related (to Ps. 26:4f.): I HAVE NOT DWELT WITH FALSE PEOPLE… I HAVE HATED THE COMMUNITY OF EVILDOERS, < AND WILL NOT DWELL WITH THE WICKED >. I HAVE NOT DWELT WITH FALSE PEOPLE. These are the people of the Tower < of Babel >, who were < in fact > false people. They went and said to Abraham: Come and dwell with us, since you are a valiant man, for we see that the Holy One has made his dwelling above and left us below. The Holy Spirit, however, cries out (in Is. 57:20): BUT THE WICKED ARE LIKE THE TROUBLED SEA. You could not dwell in security even for one hour. (Ps. 82:5:) THEY HAVE NOT KNOWN, AND THEY WILL NOT UNDERSTAND; THEY WILL WALK ABOUT IN DARKNESS. THEY HAVE NOT KNOWN. This is the generation of Enosh⁹⁶See Gen. 4:26, which rabbinic texts interpret to mean that in the days of Enosh people began practicing idolatry. AND THEY WILL NOT UNDERSTAND. [This is] the generation of the flood. THEY WILL WALK ABOUT IN DARKNESS. This is the generation of the Tower < of Babel >. Abraham said to them: What are you seeking from the Holy One who dwells above? Has he perhaps said to you: Come, labor and provide⁹⁷Gk.: pronoos, i.e., “thinking beforehand.” for me? He creates, and he provides; he makes, and he sustains. What do you want from him? (Gen. 11:4:) {THEY SAID TO HIM} [THEN THEY SAID]: COME, LET US BUILD FOR OURSELVES A CITY AND A TOWER. Then let us place our idols above him and make war with him. It is so stated (ibid., cont.): AND LET US MAKE A NAME (i.e., a god) FOR OURSELVES.⁹⁸See M.Pss. 74:2. Thus it is < also > written (in Exod. 23:13): YOU SHALL NOT MENTION THE NAME OF OTHER GODS. Abraham said to them: What are all these for? They said to him: Lest he do to us something like what he did to earlier generations. He said to them: You have forsaken (what Prov. 18:10 calls) A TOWER OF STRENGTH, THE NAME OF THE LORD; yet you say: AND LET US MAKE A NAME (i.e., a god) FOR OURSELVES! What did the Holy One do? He dispersed them, as stated (in Gen. 11:8): SO THE LORD DISPERSED THEM. Now to what extent had they built and ascended the Tower? The Holy One was deriding them, as stated (in Ps. 2:4): THE ONE WHO DWELLS IN THE HEAVENS WILL LAUGH; < THE LORD WILL DERIDE THEM >. When they had gone up above on the Tower, < there follows > immediately (in vs. 5): THEN HE WILL SPEAK UNTO THEM IN HIS WRATH…. So it (the Tower) fell from on high, as stated (in Ps. 5:11 [10]): CONDEMN THEM, O GOD, LET THEM FALL BY THEIR OWN COUNSELS. Thus Abraham had no dealings with them. Then the Holy One looked down upon them and saw them, as stated (in Ps. 53: 3f. [2f.]): {THE LORD} [GOD] OF HEAVEN LOOKED DOWN UPON THE CHILDREN OF ADAM … ALL OF THEM ARE DROSS…. When they became dross, they made themselves deities. (Ibid., cont.:) THERE IS NONE WHO DOES GOOD, NOT EVEN ONE. From here you learn that Abraham was not one of them. The ONE mentioned here is none but Abraham, as stated (in Ezek. 33:24): ABRAHAM WAS ONE AND HE INHERITED THE LAND. Abraham began saying (in Ps. 26:4f.): I HAVE NOT DWELT WITH FALSE PEOPLE; I HAVE HATED THE COMMUNITY OF EVILDOERS. It is therefore stated (in Gen. 20:1): THEN ABRAHAM JOURNEYED FROM THERE.

Chapter (81) 82: Torah [1] "And Jacob called unto his sons" (Genesis 49:1). The scriptures say: "For Sheol will not praise you (Isaiah 38:18), it was not for you to say 'let Esau be called to his sons,' as he was the firstborn, and why did he not perform the duty of honoring (i.e. burying) his father Isaac, but rather Jacob did it? It is because in the custom of the world, a murderer does not perform the duty of honoring, for he does not know when he will die, and who performs the duty of honoring for the fathers who died in their beds. Thus, Esau was not allowed to perform the duty of honoring, as he was a murderer, as it is said 'Now, therefore, let me get some game and make me savory food, that you may eat, and bless me' (Genesis 27:31), and 'For my soul is weary of murderers' (Jeremiah 4:31), and tired only means killing, as it is said 'Woe is me! For my soul is weary of murderers' (Jeremiah 4:31). Therefore, he did not call his sons, as it is said 'They do not know nor do they understand; they walk in darkness' (Psalms 82:5). Therefore, 'For Sheol will not praise you' (Isaiah 38:18), but a father will inform his sons, and he will call Jacob."
