1For every high priest, being taken from among men, is appointed for men in things pertaining to God, that he may offer both gifts and sacrifices for sins. 2The high priest can deal gently with those who are ignorant and going astray, because he himself is also surrounded with weakness. 3Because of this, he must offer sacrifices for sins for the people, as well as for himself. 4Nobody takes this honor on himself, but he is called by God, just like Aaron was. 5So also Christ didn’t glorify himself to be made a high priest, but it was he who said to him,
“You are my Son.
Today I have become your father.”
6As he says also in another place,
“You are a priest forever,
after the order of Melchizedek.”
7He, in the days of his flesh, having offered up prayers and petitions with strong crying and tears to him who was able to save him from death, and having been heard for his godly fear, 8though he was a Son, yet learned obedience by the things which he suffered. 9Having been made perfect, he became to all of those who obey him the author of eternal salvation, 10named by God a high priest after the order of Melchizedek.
11About him we have many words to say, and hard to interpret, seeing you have become dull of hearing. 12For although by this time you should be teachers, you again need to have someone teach you the rudiments of the first principles of the revelations of God. You have come to need milk, and not solid food. 13For everyone who lives on milk is not experienced in the word of righteousness, for he is a baby. 14But solid food is for those who are full grown, who by reason of use have their senses exercised to discern good and evil.
Aaron was the son of Amram and Jochebed, the brother of Moses and Miriam. He was the first priest of the people of Israel. He was appointed by God to be a spokesman for Moses when Moses went before the Pharaoh of Egypt to demand that Pharaoh would release the people of Israel from slavery. When facing Pharaoh, it was Aaron who threw his rod before Pharaoh, which turned into a snake. He also assisted Moses in declaring various judgments on Pharaoh and the Egyptian people until finally the Pharaoh conceded to the demand.
Aaron was also present at Sinai when Moses received the Ten Commandments, but he also conceded to the creation of the Golden Calf by the Israelites during the time that Moses was on the mountain receiving the law of God.
Aaron was important for the development of the priesthood in Israel, and had two sons who died, and Eleazar and Ithamar succeeded him as priests. After his death, he was buried on Mt. Hor.
