Leviticus 22:25-27

New Century Version

²⁵ and you must not take such animals from foreigners as sacrifices to the Lord. Because the animals have been hurt in some way and have something wrong with them, they will not be accepted for you.’”

²⁶ The Lord said to Moses, ²⁷ “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.
