Leviticus 22:25-27

American Standard Version

²⁵ Neither from the hand of a foreigner shall ye offer the bread of your God of any of these; because their corruption is in them, there is a blemish in them: they shall not be accepted for you.

²⁶ And Jehovah spake unto Moses, saying, ²⁷ When a bullock, or a sheep, or a goat, is brought forth, then it shall be seven days under the dam; and from the eighth day and thenceforth it shall be accepted for the oblation of an offering made by fire unto Jehovah.
