Jeremiah 11:10

11:10 They have gone back to the evil ways of their ancestors of old who refused to obey what I told them. They, too, have paid allegiance to other gods and worshiped them. Both the nation of Israel and the nation of Judah have violated the covenant I made with their ancestors.

Jeremiah 34:18

34:18 I will punish those people who have violated their covenant with me. I will make them like the calf they cut in two and passed between its pieces. I will do so because they did not keep the terms of the covenant they made in my presence.
