Midras Yesaya 44:1: Midrash Tanchuma & Midrash Tehillim

Thy right hand, O Lord (Exod. 15:6). This verse indicates that the Lord’s right hand is stretched out to receive repentant sinners. Though You set a time for the generation of the flood in which to do penance, as it is said: My spirit shall not abide in man forever (Gen. 6:3), You did not decree their destruction until they committed their most evil acts before You. Similarly, You set a time limit in which the men of the Tower of Babel were to repent, yet You did not decree their extinction until they performed their most wicked acts, as it is said: And now nothing will be withholden from them (ibid. 11:6). The expression and now is employed only to signify that they had an opportunity to repent, as is said: And now, Israel, what doth the Lord thy God require of thee? (Deut. 10:12); And now, O Israel, hearken unto the statutes (ibid. 4:1); And yet now hear, O Jacob (Isa. 44:1).

Another thing to the conductor, to serve God. What did David see fit to say to the servant of God? To teach you that anyone who repents for their sins, the Almighty adds honor to them and calls them a beloved name. Come and see this in the case of the sons of Korah: until they repented, they were not called beloved, but after they repented, they were called beloved (Psalms 45:1). To the conductor, on Shoshanim. When they repented, they were called friends, as it says, "To the conductor, on the Shoshanim, for the sons of Korah, a maskil, a song of friendship" (Psalms 47:1). You also find this with David, as until he repented, he was not included in the upper assembly, but after he repented, he was included in the upper assembly and was called the servant of God, to the conductor, for the servant of God. You will find that anyone who calls themselves a servant, the Almighty calls them a servant. Abraham called himself a servant (Genesis 18:3), "My lord, if now I have found favor in your sight, do not pass on by your servant." And the Almighty called him a servant (Genesis 26:24), "Because Abraham obeyed Me and kept My charge, My commandments, My statutes, and My laws." Jacob called himself a servant (Genesis 32:11), "I am not worthy of all the mercies, and of all the truth, which You have shown to Your servant." And the Almighty called him a servant (Isaiah 44:1), "But now listen, O Jacob, My servant." Moses called himself a servant (Deuteronomy 3:24), "O Lord God, You have begun to show Your servant Your greatness and Your mighty hand." And the Almighty called him a servant (Numbers 12:7), "Not so with My servant Moses." David called himself a servant (Psalms 116:16), "Truly, I am Your servant, the son of Your maidservant." And the Almighty called him a servant (2 Samuel 3:18), "By the hand of David, My servant, I will save." And there were those who did not call themselves servants, but the Almighty called them servants. Isaac did not call himself a servant, but the Almighty called him a servant (Exodus 32:13), "Remember Abraham, Isaac, and Israel, Your servants." Joshua did not call himself a servant, but he was called a servant (Joshua 24:29), "And Joshua, the son of Nun, the servant of the Lord, died.

"I will give thanks to the Lord with all my heart. What is the secret of the upright, and the testimony that the Lord reveals to Israel? As it is said (Amos 3:7), "For the Lord God does nothing without revealing his secret to his servants the prophets." And Israel is called prophets, as it says (Isaiah 44:1-2), "But now, hear, O Jacob My servant, and Israel whom I have chosen! Thus says the Lord who made you and formed you from the womb, who will help you, 'Do not fear, O Jacob My servant; and you Jeshurun whom I have chosen.' For I will pour out water on the thirsty land and streams on the dry ground; I will pour out My Spirit on your offspring and My blessing on your descendants. And they need to be taught only by the Lord, as it says (Isaiah 48:17), "Thus says the Lord, your Redeemer, the Holy One of Israel, 'I am the Lord your God, who teaches you to profit, who leads you in the way you should go.'"
