13“This is what the LORD, the God of Israel, says: I made a covenant with your forefathers when I brought them out of the land of Egypt, out of the house of slavery, saying:
14Every seventh year, each of you must free his Hebrew brother who has sold himself to you. He may serve you six years, but then you must let him go free. But your fathers did not listen or incline their ear.
15Recently you repented and did what pleased Me; each of you proclaimed freedom for his neighbor. You made a covenant before Me in the house that bears My Name.
16But now you have changed your minds and profaned My name. Each of you has taken back the menservants and maidservants whom you had set at liberty to go wherever they wanted, and you have again forced them to be your slaves.
— Jeremiah 34:13-16
