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.
And the man that will do presumptuously, and will not hearken unto the priest that standeth to minister there before the LORD thy God, or unto the judge, even that man shall die: and thou shalt put away the evil from Israel.
and he spake unto Korah and unto all his company, saying, Even to morrow the LORD will shew who are his, and who is holy; and will cause him to come near unto him: even him whom he hath chosen will he cause to come near unto him.
and he shall have it, and his seed after him, even the covenant of an everlasting priesthood; because he was zealous for his God, and made an atonement for the children of Israel.
And thou shalt gird them with girdles, Aaron and his sons, and put the bonnets on them: and the priest's office shall be their's for a perpetual statute: and thou shalt consecrate Aaron and his sons.
