[188] WHEN what has been described was brought to a conclusion, gifts not being yet presented, God appeared to Moses, and enjoined him to bestow the high priesthood upon Aaron his brother, as upon him that best of them all deserved to obtain that honor, on account of his virtue. And when he had gathered the multitude together, he gave them an account of Aaron's virtue, and of his good-will to them, and of the dangers he had undergone for their sakes. Upon which, when they had given testimony to him in all respects, and showed their readiness to receive him, Moses said to them, "O you Israelites, this work is already brought to a conclusion, in a manner most acceptable to God, and according to our abilities. And now since you see that he is received into this tabernacle, we shall first of all stand in need of one that may officiate for us, and may minister to the sacrifices, and to the prayers that are to be put up for us. And indeed had the inquiry after such a person been left to me, I should have thought myself worthy of this honor, both because all men are naturally fond of themselves, and because I am conscious to myself that I have taken a great deal of pains for your deliverance; but now God himself has determined that Aaron is worthy of this honor, and has chosen him for his priest, as knowing him to be the most righteous person among you. So that he is to put on the vestments which are consecrated to God; he is to have the care of the altars, and to make provision for the sacrifices; and he it is that must put up prayers for you to God, who will readily hear them, not only because he is himself solicitous for your nation, but also because he will receive them as offered by one that he hath himself chosen to this office." ¹ The Hebrews were pleased with what was said, and they gave their approbation to him whom God had ordained; for Aaron was of them all the most deserving of this honor, on account of his own stock and gift of prophecy, and his brother's virtue. He had at that time four sons, Nadab, Abihu, Eleazar, and Ithamar.
