Jeremiah 7:22-23

For concerning the matter of holocausts and sacrifices, I did not speak with your fathers, and I did not instruct them, in the day when I led them away from the land of Egypt. But on this matter I did instruct them, saying: Listen to my voice, and I will be your God, and you will be my people. And walk in the entire way that I have commanded you, so that it may be well with you.
