Leviticus 22:27-33

²⁷As for a calf, or a sheep, or a goat, whenever it is born, then shall it be seven days under its mother; and on the eighth day and after they shall be accepted for sacrifices, a burnt offering to the Lord.

²⁸And a bullock and a ewe, it and its young, you shall not kill in one day.

²⁹And if you should offer a sacrifice, a vow of rejoicing to the Lord, you° shall offer it so as to be accepted for you.

³⁰In that same day it shall be eaten; you° shall not leave of the flesh till the morrow: I am the Lord.

³¹And you° shall keep my commandments and do them.

³²And you° shall not profane the name of the Holy One, and I will be sanctified in the midst of the children of Israel. I am the Lord that sanctifies you,

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