Deuteronomy 15:21-25

But if it has any impairment, such as a limp, or blindness, or any serious impairment, you shall not sacrifice it to the Lord your God.

You shall eat it within your gates; the unclean and the clean alike may eat it, as a gazelle or a deer.

Only you shall not eat its blood; you are to pour it out on the ground like water.
