Leviticus 22:27-29

Amplified Bible, Classic Edition

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

²⁸ And whether [the mother] is a cow or a ewe, you shall not kill her and her young both in one day.

²⁹ And when you sacrifice an offering of thanksgiving to the Lord, sacrifice it so that you may be accepted.
