Deuteronomy 15:21-23

21But if there be a defect therein, [if it be] lame, or blind, [or have] any evil defect, thou shalt not sacrifice it to Jehovah thy 1God. 22In thy gates shalt thou eat it; the unclean and the clean [shall eat it] alike, as the gazelle and as the hart. 23Only thou shalt not eat the blood thereof: thou shalt pour it upon the earth as water.
