Jeremiah 34:13-16

13‘The Lord, Israel's God, says this to the people: I made a covenant with your ancestors when I brought them out of Egypt. They had been slaves when they were there.

14I told them, “When any Hebrew slave has worked for you for six years, you must let them go free. In the seventh year after they sold themselves to you, you must set them free.” But your ancestors did not listen to me. They did not obey me.

15But now, you yourselves agreed to do what pleases me. You decided to obey me. You made a serious agreement with me in the temple which is my home. You let your slaves go free.

16But now you have turned back to your old ways. You have refused to give me honour. You had let your slaves go free, as they wanted to do. But now you have forced them to work for you as your slaves again.
