Hebrews 5:4-10

4And no man taketh this honour to himself, but he that is called by God, as was Aaron. 5So also Christ glorified not himself to be made an high priest; but he that said to him, Thou art my Son, to day have I begotten thee. 6As he saith also in another place, Thou art a priest for ever after the order of Melchizedek. 7Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears to him that was able to save him from death, and was heard in that he feared;1 8Though he was a Son, yet he learned obedience by the things which he suffered; 9And being made perfect, he became the author of eternal salvation to all them that obey him;

10Called by God an high priest after the order of Melchizedek.
