Jeremiah 11:4

11:4 Those are the terms that I charged your ancestors to keep when I brought them out of Egypt, that place which was like an iron-smelting furnace. I said at that time, “Obey me and carry out the terms of the agreement exactly as I commanded you. If you do, you will be my people and I will be your God.

Jeremiah 11:7

11:7 For I solemnly warned your ancestors to obey me. I warned them again and again, ever since I delivered them out of Egypt until this very day.
