Yermiyah/Jeremiah 34:8 - 22, 33:25 - 26
8 The word that came to Jeremiah from Hashem, after King Zedekiah sealed a covenant with the entire people that was in Jerusalem, to proclaim freedom for them, 9 that every man set free his bondsman and his bondswoman, the Jew and the Jewess; that no man should enslave his fellow Jew. 10 All the leaders and the entire people who entered into the covenant hearkened — that every man should set free his bondsman and every man his bondswoman, not to enslave them further; they hearkened and they sent them off.
11 But after that they reversed themselves and brought back the bondsmen and bondswomen whom they had set free, and subjugated them as slaves and maidservants.
12 Then the word of Hashem came to Jeremiah, from Hashem, saying, 13 "So says Hashem, God of Israel. I sealed a covenant with your forefathers on the day I took them out of the land of Egypt, from the house of slaves, saying, 14 'At the end of seven years each of you shall set free his Jewish brother who will be sold to you; he shall serve you for six years and then you shall set him free from yourself.' But your fathers did not hearken to Me, not did they incline their ear. 15 Today you repented and did what is just in My eyes - for every man to proclaim freedom for his fellow, and you sealed a covenant before Me in the Temple upon which My Name is called. 16 Then you reversed yourselves and desecrated My Name, and every man brought back his bondsman and every man his bondswoman whom you set free on their own, and you subjugated them to be slaves and maidservants to you."
17 "Therefore, so says Hashem, 'You did not hearken to Me to proclaim freedom, every man for his brother and every man for his fellow; behold! — I proclaim you to be free — the words of Hashem — for the sword, for the plague, and for the famine, and I shall make you an object of trepidation for all the kingdoms of the earth. 18 I shall give the people who violated My covenant — those who did not uphold the words of the covenant they sealed before Me, the calf that they cut in two and passed between its parts, 19 the leaders of Judah and the leaders of Jerusalem, the officers and the Kohanim and all the people of the Land, who passed through the parts of the calf. 20 I shall give them into the hand of their enemies and into the hand of those who seek their lives; their corpses will be carrion for the bird of heaven and the beast of the field. 21 And Zedekiah, king of Judah, and his leaders I shall give into the hand of their enemies and into the hand of those who seek their lives, and into the hand of the army of the king of Babylon, who have advanced away from you. 22 Behold! I have commanded — the words of Hashem — and I shall return them to this city and they shall wage war against it, conquer it and burn it in fire; and I shall make the cities of Judah desolate, without an inhabitant.' "
25 So says Hashem, "Were it not for My covenant day and night, had I not established the laws of heaven and earth. 26 then I might abominate the offspring of Jacob and David, not to take of its offspring as rulers over the offspring of Abraham, Isaac, and Jacob; for I shall bring back their captivity and show them mercy."
