Not to eat the flesh of beasts set apart as sacrifices, that have been rendered unfit to be offered up by deliberately inflicted blemish

Maimonides

Not to eat the flesh of beasts set apart as sacrifices, that have been rendered unfit to be offered up by deliberately inflicted blemish, as it is said, “Thou shalt not eat any abominable thing” (Deut. 14:3). We learn by tradition that this text refers to sacrificial beasts rendered unfit by the infliction of a blemish.
