Deuteronomy 15:21-23

21But if this firstborn animal has any defect, such as lameness or blindness, or if anything else is wrong with it, you must not sacrifice it to the Lord your God.

22Instead, use it for food for your family in your hometown. Anyone, whether ceremonially clean or unclean, may eat it, just as anyone may eat a gazelle or deer.

23But you must not consume the blood. You must pour it out on the ground like water.
