Deuteronomy 15:23

²¹  And if there be any blemish therein, as if it be lame, or blind, or have any ill blemish, thou shalt not sacrifice it unto the LORD thy God.

²²  Thou shalt eat it within thy gates: the unclean and the clean person shall eat it alike, as the roebuck, and as the hart.

²³  Only thou shalt not eat the blood thereof; thou shalt pour it upon the ground as water.
