Numbers 18:7

“Now as for you, bring near to yourself Aaron your brother, and his sons with him, from among the sons of Israel, to minister as priests to Me—Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

“You shall gird them with sashes, Aaron and his sons, and bind caps on them, and they shall have the priesthood by a perpetual statute. So you shall ordain Aaron and his sons.

“Bring the tribe of Levi near and have them stand before Aaron the priest, that they may minister to him.

and that He has brought you near, Korah, and all your brothers, sons of Levi, with you? And are you seeking for the priesthood also?

“And they shall thus keep your responsibility and the responsibility of all the tent, but they shall not come near to the furnishings of the sanctuary and the altar, so that neither they nor you will die.

At that time Yahweh set apart the tribe of Levi to carry the ark of the covenant of Yahweh, to stand before Yahweh to minister for Him and to bless in His name to this day.

“For the Levites have no portion among you because the priesthood of Yahweh is their inheritance. Gad and Reuben and the half-tribe of Manasseh also have received their inheritance eastward beyond the Jordan, which Moses the servant of Yahweh gave them.”

So Micah ordained the Levite, and the young man became his priest and lived in the house of Micah.

“And you have not kept the responsibility of My holy things yourselves, but you have set foreigners as keepers of the responsibility given by Me for My sanctuary.”

“Yet they shall be ministers in My sanctuary, having oversight at the gates of the house and ministering in the house; they shall slaughter the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.

“But the Levitical priests, the sons of Zadok, who kept the responsibility of My sanctuary when the sons of Israel went astray from Me, shall come near to Me to minister to Me; and they shall stand before Me to bring near to Me the fat and the blood,” declares Lord Yahweh.

“They shall enter My sanctuary; they shall come near to My table to minister to Me and keep the responsibility given by Me.

And no one takes this honor to himself, but receives it when he is called by God, even as Aaron was.
