Jeremiah 34:16

16 But then you changed your minds again and dishonored me. All of you took back the slaves whom you had set free as they desired, and you forced them into slavery again.

Jeremiah 34:16 In-Context

14 every seven years they were to set free any Hebrew slave who had served them for six years. But your ancestors would not pay any attention to me or listen to what I said.
15 Just a few days ago you changed your minds and did what pleased me. All of you agreed to set all Israelites free, and you made a covenant in my presence, in the Temple where I am worshiped.
16 But then you changed your minds again and dishonored me. All of you took back the slaves whom you had set free as they desired, and you forced them into slavery again.
17 So now, I, the Lord, say that you have disobeyed me; you have not given all Israelites their freedom. Very well, then, I will give you freedom: the freedom to die by war, disease, and starvation. I will make every nation in the world horrified at what I do to you.
18 The officials of Judah and of Jerusalem, together with the palace officials, the priests, and all the leaders, made a covenant with me by walking between the two halves of a bull that they had cut in two. But they broke the covenant and did not keep its terms. So I will do to these people what they did to the bull.
