and you shall gird them, Aaron and his sons, with sashes and tie headdresses on them, and the priesthood shall be theirs by a perpetual ordinance. You shall then ordain Aaron and his sons.
Then he spoke to Korah and all his congregation, saying, “In the morning the Lord will make known who is his and who is holy and who will be allowed to approach him; the one whom he will choose he will allow to approach him.
It shall be for him and for his descendants after him a covenant of perpetual priesthood, because he was zealous for his God and made atonement for the Israelites.’ ”
At that time the Lord set apart the tribe of Levi to carry the ark of the covenant of the Lord, to stand before the Lord to minister to him and to bless in his name, to this day.
As for anyone who presumes to disobey the priest appointed to minister there to the Lord your God or the judge, that person shall die. So you shall purge the evil from Israel.
