Hebrews 5:5-6So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee. As he saith also in another place, Thou art a priest for ever after the order of Melchisedec.
Hebrews 6:20Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec.
