Leviticus 22:8

22:8 He must not eat an animal that has died of natural causes or an animal torn by beasts and thus become unclean by it. I am the Lord.

Leviticus 22:19-23

22:19 if it is to be acceptable for your benefit it must be a flawless male from the cattle, sheep, or goats. 22:20 You must not present anything that has a flaw, because it will not be acceptable for your benefit. 22:21 If a man presents a peace offering sacrifice to the Lord for a special votive offering or for a freewill offering from the herd or the flock, it must be flawless to be acceptable; it must have no flaw.

22:22 “‘You must not present to the Lord something blind, or with a broken bone, or mutilated, or with a running sore, or with a festering eruption, or with a feverish rash. You must not give any of these as a gift on the altar to the Lord. 22:23 As for an ox or a sheep with a limb too long or stunted, you may present it as a freewill offering, but it will not be acceptable for a votive offering.
