And take thou unto thee Aaron thy 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.
a. When Israel first arrived at Sinai to receive the Law, it was the will of God that they as a nation would be a kingdom of priests to Him.
1). Exodus 19:4-6 Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself.
Exodus 19:5 Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine:
Exodus 19:6 And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
b. Israel, out of the wrong kind of fear rejected the privilege and instead chose to let someone else hear God and then tell the nation.
1). Exodus 20:18-20 And all the people saw the thunderings, and the lightnings, and the noise of the trumpet, and the mountain smoking: and when the people saw it, they removed, and stood afar off.
Exodus 20:19 And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die.
Exodus 20:20 And Moses said unto the people, Fear not: for God is come to prove you, and that his fear may be before your faces, that ye sin not.
Exodus 20:21 And the people stood afar off, and Moses drew near unto the thick darkness where God was.
c. So the priesthood was given to the family of Aaron and the tribe of Levi, of which Aaron was from, was appointed to minister in the Tabernacle.
1). Exodus 28:1
2). Numbers 18:20-23 And the LORD spake unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any part among them: I am thy part and thine inheritance among the children of Israel.
Numbers 18:21 And, behold, I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, even the service of the tabernacle of the congregation.
Numbers 18:22 Neither must the children of Israel henceforth come nigh the tabernacle of the congregation, lest they bear sin, and die.
Numbers 18:23 But the Levites shall do the service of the tabernacle of the congregation, and they shall bear their iniquity: it shall be a statute for ever throughout your generations, that among the children of Israel they have no inheritance.
1. “And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office…”
a. The original anointing of the priesthood followed the family line, just as today there are levels of generations in one family who are in the ministry.
2. “…even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.”
a. Nadab and Abihu died in the incident recorded in Leviticus 10:1 (See notes).
