Leviticus 22:26-33

GOD spoke to Moses: “When a calf or lamb or goat is born, it is to stay with its mother for seven days. After the eighth day, it is acceptable as an offering, a gift to GOD. Don’t slaughter both a cow or ewe and its young on the same day. When you sacrifice a Thanksgiving-Offering to GOD, do it right so it will be acceptable. Eat it on the same day; don’t leave any leftovers until morning. I am GOD. “Do what I tell you; live what I tell you. I am GOD. “Don’t desecrate my holy name. I insist on being treated with holy reverence among the People of Israel. I am GOD who makes you holy and brought you out of Egypt to be your God. I am GOD.”
