Hebrews 5:4-6

Living Bible

⁴ Another thing to remember is that no one can be a high priest just because he wants to be. He has to be called by God for this work in the same way God chose Aaron.

⁵ That is why Christ did not elect himself to the honor of being High Priest; no, he was chosen by God. God said to him, “My Son, today I have honored you.”^{[a] 6} And another time God said to him, “You have been chosen to be a priest forever, with the same rank as Melchizedek.”
