Jeremias (Jeremiah) 7:22-23

For I spoke not to your fathers, and I commanded them not, in the day that I brought them out of the land of Egypt, concerning the matter of burnt-offerings and sacrifices. But this thing I commanded them, saying: Hearken to my voice, and I will be your God and you shall be my people. And walk ye in all the way that I have commanded you, that it may be well with you.
