Deuteronomy 15:21-25

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.

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

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