Leviticus 22:26-33

The LORD said to Moses, “When an ox, a sheep, or a goat is born, it must stay seven days with its mother. But from the eighth day on, this animal will be accepted as a sacrifice by fire to the LORD. But you must not kill the animal and its mother on the same day, either an ox or a sheep. “If you want to offer some special offering of thanks to the LORD, you must do it in a way that pleases him. You must eat the whole animal that same day and not leave any of the meat for the next morning. I am the LORD. “Remember my commands and obey them; I am the LORD. Show respect for my holy name. You Israelites must remember that I am holy; I am the LORD, who has made you holy. I brought you out of Egypt to be your God. I am the LORD.”
