Hebrews 5:10

And Melchizedek king of Salem brought out bread and wine; now he was a priest of God Most High.

Yahweh has sworn and will not change His mind, “You are a priest forever According to the order of Melchizedek.”

Therefore, He had to be made like His brothers in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.

Therefore, holy brothers, partakers of a heavenly calling, consider the Apostle and High Priest of our confession—Jesus,

In this way also Christ did not glorify Himself to become a high priest, but He who said to Him, “You are My Son, Today I have begotten You”;

just as He says also in another passage, “You are a priest forever According to the order of Melchizedek.”
