It is remarkable that this title occurs but seldom in the O.T. Leviticus 21:10; Numbers 35:25; Joshua 20:6; 2 Kings 12:10; 2 Chronicles 24:11 , etc. Aaron was constantly called 'the priest;' but as his sons were also called priests, he was necessarily the 'chief' and would correspond to what is called high priest in the N.T. His office is summed up in few words: he "is ordained for men in things pertaining to God" that he might offer both gifts and sacrifices for sins. He stood for the people to God: he offered up the sacrifices which put the people in relation with God (Leviticus 9 ), also those on the day of atonement (Leviticus 16 ), and he blessed them as from God. He, as taken from among men, was one who could have compassion on, or forbearance toward, the ignorant and the erring; for that he himself was compassed with infirmity. Hebrews 5:1,2 . Aaron did not take the honour upon himself, nor did Christ. Hebrews 5:4,5 . Having accomplished redemption by the offering of Himself, He passed through the heavens and sat down on the right hand of God. He is touched with the feeling of our infirmities, having been Himself tempted as we are, apart from sin. He ever lives to make intercession for us, He is also the minister of the sanctuary — He appears in the presence of God for us, and is the great Priest over the house of God. Hebrews 4:14,15; Hebrews 8:1 , etc. See AARON, AARONIC PRIESTHOOD, MELCHISEDEC.
