Deuteronomy 15:19-23 - Consecration Of Firstborn Animals
19 "Every firstling male that is born of your herd and of your flock you shall consecrate to Yahweh your God; you shall not do work with the firstling of your ox, and you shall not shear the firstling of your flock. 20 [Rather] {before Yahweh} your God you shall eat it year by year at the place Yahweh will choose, you and your household. 21 But if there is a physical defect in it, [such as] lameness or blindness, any serious defect, you shall not sacrifice it to Yahweh your God. 22 In your {towns} you shall eat it, the unclean and the clean together [may eat it], [just] as [they eat] the gazelle and as [they eat] the deer. 23 But you shall not eat its blood; you shall pour it on the ground like water."
