Hebrews 5:4-10
5:4 And no one assumes this honor on his own initiative, but only when called to it by God, as in fact Aaron was.
5:5 So also Christ did not glorify himself in becoming high priest, but the one who glorified him was God, who said to him, “You are my Son! Today I have fathered you,”
5:6 as also in another place God says, “You are a priest forever in the order of Melchizedek.”
5:7 During his earthly life Christ offered both requests and supplications, with loud cries and tears, to the one who was able to save him from death and he was heard because of his devotion.
5:8 Although he was a son, he learned obedience through the things he suffered.
5:9 And by being perfected in this way, he became the source of eternal salvation to all who obey him,
5:10 and he was designated by God as high priest in the order of Melchizedek.
