These are the names of the sons of Aaron, the priests which were anointed, whom he consecrated to minister in the priest's office.
And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.
Thus shalt thou separate the Levites from among the children of Israel: and the Levites shall be mine.
At that time the LORD separated the tribe of Levi, to bear the ark of the covenant of the LORD, to stand before the LORD to minister unto him, and to bless in his name, unto this day.
