"Tell Aaron and his sons to keep away from the holy things of the people of Israel, which they dedicate to me, so that they may not profane my holy name; I am the LORD.
Say to them, `If any one of all your descendants throughout your generations approaches the holy things, which the people of Israel dedicate to the LORD, while he has an uncleanness, that person shall be cut off from my presence: I am the LORD.
None of the line of Aaron who is a leper or suffers a discharge may eat of the holy things until he is clean. Whoever touches anything that is unclean through contact with the dead or a man who has had an emission of semen,
But if a priest's daughter is a widow or divorced, and has no child, and returns to her father's house, as in her youth, she may eat of her father's food; yet no outsider shall eat of it.
"Say to Aaron and his sons and all the people of Israel, When any one of the house of Israel or of the sojourners in Israel presents his offering, whether in payment of a vow or as a freewill offering which is offered to the LORD as a burnt offering,
And when any one offers a sacrifice of peace offerings to the LORD, to fulfil a vow or as a freewill offering, from the herd or from the flock, to be accepted it must be perfect; there shall be no blemish in it.
Animals blind or disabled or mutilated or having a discharge or an itch or scabs, you shall not offer to the LORD or make of them an offering by fire upon the altar to the LORD.
neither shall you offer as the bread of your God any such animals gotten from a foreigner. Since there is a blemish in them, because of their mutilation, they will not be accepted for you."
"When a bull or sheep or goat is born, it shall remain seven days with its mother; and from the eighth day on it shall be acceptable as an offering by fire to the LORD.
