Hebrews 5:1-11 The Son Is Qualified To Be A High Priest Forever.
The high priest is a mediator, “appointed for men in things pertaining to God” (v. 1a). Our author made this point earlier. Our high priest is able to both sympathize with us, but also be the propitiation for us, in that He lived a sinless life (2:17-18; 4:15). He is able to both sympathize with us, and “have compassion on those who are ignorant and going astray” (v. 2a). Where the Son is different from other high priests is that he was sinless. He had the weaknesses associated with being human, but not in that of sin. Others had to offer sacrifices for sins, but the son offered up Himself. He did however share the honour of being called and appointed by the Father, as all high priests are (vv. 3-4, 10). Speaking of Christ, the Anointed One, he again appeals to a couple of quotes to prove his point.
First there is the declaration of verse 5, echoing Psalm 2:7 (Cf. John 8:54). He then couples this with Psalm 110:4, where we learn of the Priest-King to come-“according to the order of Melchizedek” (v. 6 Cf. 7:17). The Son had offered up prayers and supplications, “and was heard because of His godly fear,” and in doing so gave us an example to follow (v. 7 Cf. Ps. 22:1; Mt. 26:39, 42, 44, 53; Mk. 14:36, 39; Lk. 22:41). However, as a man, He also “learned obedience by the things He suffered,” also setting an example for us (v. 8 Cf. Phil. 2:8). It was His obedience that made Him the perfect substitutionary sacrifice for us, who are also empowered to obey (v. 9 Cf. 2:10). Our author wanted to continue on this line of thought, but sadly many in his audience had “become dull of hearing” (v. 11 Cf. Mt. 13:14-15; Is. 6:9-10).
