Jeremiah 11:3-4

Tell them that the LORD, the God of Israel, says, ‘Anyone who does not keep the terms of the covenant will be under a curse. 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.
