Deuteronomy 15:19-23 - Consecration Of Firstborn Animals
19 Every firstling that is brought forth in thy herd and in thy flock that is a male, shalt thou hallow unto Yahweh thy God, - thou shalt not work with a firstling of thine oxen, neither shalt thou shear a firstling of thy flock: 20 before Yahweh thy God, shalt thou eat it year by year, in the place which Yahweh shall choose, - thou, and thy households. 21 But, when there is in it any blemish, lameness or blindness, any ill blemish, thou shalt not sacrifice it unto Yahweh thy God: 22 within thine own gates, mayest thou eat it, - the unclean of you and the clean alike, as the gazelle and as the hart. 23 Only the blood thereof, shalt thou not eat, - on the earth, shalt thou pour it out like water.
