Leviticus 22:27-33

²⁷“When a bull, a sheep, or a goat is born, it shall remain seven days with its mother. From the eighth day on it shall be accepted for the offering of an offering made by fire to the LORD.

²⁸Whether it is a cow or ewe, you shall not kill it and its young both in one day.

²⁹“When you sacrifice a sacrifice of thanksgiving to the LORD, you shall sacrifice it so that you may be accepted.

³⁰It shall be eaten on the same day; you shall leave none of it until the morning. I am the LORD.

³¹“Therefore you shall keep my commandments, and do them. I am the LORD.

³²You shall not profane my holy name, but I will be made holy amongst the children of Israel. I am the LORD who makes you holy,

³³who brought you out of the land of Egypt, to be your God. I am the LORD.”
