'Minister as Priests' in the Bible

Thou thyself, therefore bring near unto thee - Aaron thy brother and his sons with him out of the midst of the sons of Israel, that they may minister as priests unto me, - Aaron, Nadab and Abihu, Eleazar and Ithamar sons of Aaron.

And thou shalt clothe therewith Aaron thy brother, and his sons, with him, - and shalt anoint them and install them, and hallow them, so shall they minister as priests unto me.

And, his, is the thing which thou shalt do to them to hallow them, that they may minister as priests unto me, - Take one young bullock and two rams without defect;

Thus will I hallow the tent of meeting, and the altar, - and, Aaron and his sons, will I hallow, to minister as priests unto me.

Aaron also, and his sons, shalt thou anoint, - so shalt thou hallow them to minister as priests unto me.

and shalt anoint them as thou didst anoint their father, and they shall minister as priests unto me, - so shall their anointing remain to them for an age-abiding priesthood, to their generations.

This, is what pertaineth to the anointing of Aaron and to the anointing of his sons out of the altar-flames of Yahweh, - granted in the day when he brought them near, to minister as priests unto Yahweh:

These, are the names of the sons of Aaron, the priests that were anointed, - who were installed to minister as priests.

So then they shall not come near unto me To minister as priests unto me, Nor come near unto any of my holy things, As regardeth things most holy, - But they shall bear their rebuke, and their abominations which they have committed;
