Deuteronomy 15:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ But if it has any defect—any serious defect, such as lameness or blindness—you shall not sacrifice it to the Lord your God; ²² within your towns you may eat it, the unclean and the clean alike, as you would a gazelle or deer. ²³ Its blood, however, you must not eat; you shall pour it out on the ground like water.
