And you shall gird them with belts, Aaron and his sons, and put the turbans on them: and the priest's office shall be theirs for a perpetual statute: and you shall consecrate Aaron and his sons.
In the tabernacle of meeting outside the veil, which is before the testimony, Aaron and his sons shall tend it from evening to morning before the LORD: it shall be a statute forever unto their generations on the behalf of the children of Israel.
And take unto you Aaron your brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
For Moses had said, Consecrate yourselves today to the LORD, even every man upon the cost of his son, and his brother; that he may bestow upon you a blessing this day.
And you shall anoint them, as you did anoint their father, that they may minister unto me in the priest's office: for their anointing shall surely be an everlasting priesthood throughout their generations.
And you shall not go out of the door of the tabernacle of meeting in seven days, until the days of your consecration be at an end: for seven days shall he consecrate you.
To be a memorial unto the children of Israel, that no stranger, who is not of the descendants of Aaron, come near to offer incense before the LORD; that he become not as Korah, and as his company: as the LORD said to him by the hand of Moses.
Therefore you and your sons with you shall keep your priest's office for everything at the altar, and within the veil; and you shall serve: I have given your priest's office unto you as a gift for service: and the stranger that comes near shall be put to death.
And he shall have it, and his descendants 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.
Therefore the LORD God of Israel says, I said indeed that your house, and the house of your father, should walk before me forever: but now the LORD says, Be it far from me; for them that honor me I will honor, and they that despise me shall be lightly esteemed.
