2"Tell Aaron and his sons to treat with respect the sacred offerings the Israelites consecrate to me, so they will not profane my holy name. I am the LORD.
3"Say to them: 'For the generations to come, if any of your descendants is ceremonially unclean and yet comes near the sacred offerings that the Israelites consecrate to the LORD, that person must be cut off from my presence. I am the LORD.
4"'If a descendant of Aaron has a defiling skin disease or a bodily discharge, he may not eat the sacred offerings until he is cleansed. He will also be unclean if he touches something defiled by a corpse or by anyone who has an emission of semen,
9"'The priests are to perform my service in such a way that they do not become guilty and die for treating it with contempt. I am the LORD, who makes them holy.
13But if a priest's daughter becomes a widow or is divorced, yet has no children, and she returns to live in her father's household as in her youth, she may eat her father's food. No unauthorized person, however, may eat it.
18"Speak to Aaron and his sons and to all the Israelites and say to them: 'If any of you--whether an Israelite or a foreigner residing in Israel--presents a gift for a burnt offering to the LORD, either to fulfill a vow or as a freewill offering,
21When anyone brings from the herd or flock a fellowship offering to the LORD to fulfill a special vow or as a freewill offering, it must be without defect or blemish to be acceptable.
22Do not offer to the LORD the blind, the injured or the maimed, or anything with warts or festering or running sores. Do not place any of these on the altar as a food offering presented to the LORD.
25and you must not accept such animals from the hand of a foreigner and offer them as the food of your God. They will not be accepted on your behalf, because they are deformed and have defects.'"
27"When a calf, a lamb or a goat is born, it is to remain with its mother for seven days. From the eighth day on, it will be acceptable as a food offering presented to the LORD.
