And take you to you Aaron your brother, and his sons with him, from among the children of Israel…
Previous to this time, there was probably no separate order of priesthood in the Church of God; but every father was the priest of his family, as in killing the lamb of the passover and sprinkling the blood, or each worshipper had been at liberty to transact the business of sacrifice as he pleased. So far, in the history of Israel as redeemed from Egypt, Moses seems to have officiated occasionally as priest, as in the case of offering the sacrifice and sprinkling the blood of the covenant; or he selected young men as temporary priests. But the erection of a special place of worship, most notably carried with it the setting up an order of priesthood, with ritual of worship. The very name "cohen," which we translate "priest," is supposed to denote the idea of a familiar friend of God. The distinctive function of the office was to receive and present to God, as His nearest friend and associate, that which belonged to Him. The three great elements entering into the idea of their position and office were:
1. That they are chosen by Jehovah Himself to be His.
2. That they are officially holy in a pre-eminent sense.
3. That they have, by reason of their election and holiness, the privilege of drawing near to God, as holding a position intermediate between man and God, and therefore of mediators.
(S. Robinson, D. D.)
