Jeremiah 7:21-23

Thus saith Jehovah of hosts, the God of Israel: Add your burnt-offerings unto your sacrifices, and eat ye flesh. For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt-offerings or sacrifices: but this thing I commanded them, saying, Hearken unto my voice, and I will be your God, and ye shall be my people; and walk ye in all the way that I command you, that it may be well with you.
