No man that has a blemish of the descendants of Aaron the priest shall come near to offer the offerings of the LORD made by fire: he has a blemish; he shall not come near to offer the bread of his God.
They shall be holy unto their God, and not profane the name of their God: for the offerings of the LORD made by fire, and the bread of their God, they do offer: therefore they shall be holy.
And he spoke unto Korah and unto all his company, saying, Even tomorrow the LORD will show who are his, and who is holy; and will cause him to come near unto him: even him whom he has chosen will he cause to come near unto him.
