Leviticus 22:27-29

Darby Translation

²⁷ An ox, or a sheep, or a goat, when it is brought forth, shall be seven days under its dam; and from the eighth day and thenceforth it shall be accepted for an offering by fire to Jehovah.

²⁸ A cow, or sheep—it and its young shall ye not slaughter in one day.

²⁹ And when ye sacrifice a sacrifice of thanksgiving to Jehovah, ye shall sacrifice it for your acceptance.
