Leviticus 22:25-28

²⁵Of the hand of an alien ye shall not offer loaves to your God, and whatever other thing he will give, for all things be corrupt and defouled; ye shall not receive those or them.

²⁶And the Lord spake to Moses, and said,

²⁷When an ox, sheep, and goat be brought forth of the mother’s womb, in seven days those or they shall be under the teat of their mother; soothly in the eighth day, and from thenceforth, those or they may be offered to the Lord,

²⁸whether that is a cow, whether a sheep; those or they shall not be offered in one day with their fruits.
