Hebrews 5:4-6

Amplified Bible, Classic Edition

⁴ Besides, one does not appropriate for himself the honor [of being high priest], but he is called by God and receives it of Him, just as Aaron did.

⁵ So too Christ (the Messiah) did not exalt Himself to be made a high priest, but was appointed and exalted by Him Who said to Him, You are My Son; today I have begotten You;^(A)

⁶ As He says also in another place, You are a Priest [appointed] forever after the order (with ^[a]the rank) of Melchizedek.^(B)
