Deuteronomy 15:19-23 - Consecration Of Firstborn Animals
19 All the first-born that shall be brought forth among thy cattle and among thy sheep, the male thou shalt consecrate to Jehovah thy God: thou shalt not work with the first-born of thy bullock, and thou shalt not shear first-born of thy sheep. 20 Before Jehovah thy God thou shalt eat it year by year, in the place which Jehovah shall choose, thou, and thy house. 21 And when a blemish shall be in it, lame or blind, any evil blemish, thou shalt not sacrifice it to Jehovah thy God. 22 In thy gates thou shalt eat it: the unclean and the clean together, as the roe and the stag. 23 Only its blood thou shalt not eat: upon the earth shalt thou pour it as water.
