In the Bible, Melchizedek, 'king of righteousness'  also transliterated Melchisedech or Malki Tzedek, was the king of Salem and priest of El Elyon (often translated as 'most high God').

He is first mentioned in Genesis 14:18–20,[2] where he brings out bread and wine and then blesses Abram and El Elyon.

He is also mentioned in the Books of Psalms 110:4 where King David is told that he is "a priest for ever after the manner of Melchizedek."

In Christianity, according to the Epistle to the Hebrews, Jesus Christ is identified as "High priest forever in the order of Melchizedek", and so Jesus assumes the role of High Priest once and for all. 

Melchizedek is the first person in the Torah to be titled a Kohen (priest).
