“And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the Most High God. And he blessed him, and said, Blessed be Abram of the Most High God, Possessor of heaven and earth…” Genesis 14:18-19 (KJV)

Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus; who was faithful to Him that appointed Him, as also Moses was faithful in all His house.” Hebrews 3:1-2

“So 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.” Hebrews 5:5
