Midrasz do Lamentacje Jeremiasza 3:22

“It is the Lord’s kindnesses that have not ceased, for His mercies have not ended” (Lamentations 3:22).
“It is the Lord’s kindnesses that have not ceased” – Rabbi Shimon ben Lakish said: After the Holy One blessed be He despairs of the righteous in this world, He then has mercy on them. That is what is written: “It is the Lord’s kindnesses that have not ceased.”
“They are new every morning; great is Your faithfulness” (Lamentations 3:23).
“They are new every morning; great is Your faithfulness” – Rabbi Alexandri said: Because You renew us each and every morning, we know that “great is Your faithfulness” regarding the revival of the dead. Rabbi Shimon bar Abba said: Because You renew us on the mornings of the kingdoms,⁴⁹New kingdoms arise and supplant the old ones, yet the Jewish people remain (Etz Yosef). we know that “great is Your faithfulness” to redeem us.
Rabbi Ḥelbo said: Each and every day, the Holy One blessed be He creates a band of new angels and they recite a new song and go on their way.⁵⁰They cease to exist. Rabbi Berekhya said: I responded to Rabbi Ḥelbo: ‘But is it not written: “Release me, as dawn is breaking”’ (Genesis 32:27)?⁵¹This is the guardian angel of Esau, who is still in existence. Apparently, angels do not cease to exist after only one day. He said to me: ‘Strangler, did you think you could strangle me?⁵²Did you think you could challenge me from an explicit verse? Gavriel and Mikhael are the supernal princes. All of them are replaced, but they are not replaced.’⁵³Some angels, such as Gavriel and Mikhael, and also the guardian angel of Esau, continue to exist.
Hadrian, may his bones be crushed, asked Rabbi Yehoshua ben Ḥananya, he said to him: ‘Do you say that each and every day the Holy One blessed be He creates a band of new angels and they recite a new song and go on their way?’ He said to him: ‘Yes.’ He said to him: ‘And where do they go?’ He said to him: ‘To where they were created from.’ He said to him: ‘Where are they created from?’ He said to him: ‘From the river of fire.’ He said to him: ‘How does the river of fire function?’ He said: ‘Like the Jordan, which does not stop at night and does not stop during the day.’ He said to him: ‘But the Jordan flows during the day and stops at night.’ He said to him: ‘I was watching at Beit Peor, and that Jordan, just as it flows during the day, so it flows at night.’ He said to him: ‘From where does that river of fire emerge?’ He said to him: ‘From the perspiration of the creatures that bear the Throne.’
“The Lord is my portion, says my soul; therefore I will hope in Him” (Lamentations 3:24).
“The Lord is my portion, says my soul” – Rabbi Abbahu said in the name of Rabbi Yoḥanan: [This is analogous] to a king who entered a province, and there were generals, captains, and commanders with him. The prominent leaders of the province resided in the middle of the province. One said: ‘I will take the generals to me.’ One said: ‘I will take the captains to me.’ One said: ‘I will take the commanders to me.’⁵⁴Each thought to curry favor with the different groups of attendants There was one clever one there. He said: ‘I will take the king, as all the others are replaced and the king is not replaced.’ Likewise, idolaters, some worship the sun, some worship the moon, some worship wood and stone. But Israel worships only the Holy One blessed be He. That is what is written: “The Lord is my portion, says my soul,” as I proclaim His unity twice daily, and say: “Hear Israel, the Lord is our God, the Lord is one” (Deuteronomy 6:4).
