In the majority of Masoretic Hebrew texts the name is written as two words, Malki-ṣedeq מלכי־צדק,
This is rendered in one word in both the Septuagint (Μελχισεδέκ) and Vulgate (Melchisedech).
The Authorised King James Version of 1611 renders the name "Melchizedek" when translating from the Hebrew, and "Melchisedec" in the New Testament.
"And Melchizedek king of Salem brought out bread and wine: and he was [is] the priest of the most high God. And he blessed him, and said, 'Blessed be Abram to the most high God, possessor of heaven and earth, And blessed be the most high God, which hath delivered thine enemies into thy hand'. And he gave him tithe from all."
— Genesis 14:18–20, King James Version
The name is composed from the two elements: melek(h), 'king', and ṣedeq, which means either 'righteousness'[9] or 'priest', or the proper name Zedek.[10][11]
The Samaritan Pentateuch reads שלמו (lit. 'his peace' or in contextual flow 'allied with him') in place of the Masoretic שלם (Salem)
Rabbis debate the role of the Zadokite priests vs. the Levite priests. Jesus, regarded in the letter as the Messiah, had a right to a priesthood pre-dating the Jewish Aaronic priesthood (Hebrews 5:5–6).[46] King David[c] who was a "righteous king" (מלכי צדק) of Salem and, like Melchizedek, had certain priest-like responsibilities. The Zohar defines the noted Melchizedek as referring to Ahron the Kohen Gadol (high priest).[42]
The name is formed in parallel with Adoni-ṣedeq אדני־צדק, also a king of Salem, mentioned in Joshua 10:1–3,[15] where the element malik ('king') is replaced by adon ('lord').[a]
11Q13 (11QMelch) is a fragment of a text, dated to the end of the second or start of the first century BC, about Melchizedek, found in Cave 11 at Qumran in the West Bank and part of the Dead Sea Scrolls. Melchizedek is seen as a divine being in the text and is referred to as "El" or "Elohim", titles usually reserved for God.[53] According to the text, Melchizedek will proclaim the "Day of Atonement" and he will atone for the people who are predestined to him. He also will judge the peoples.[54]
The Genesis Apocryphon (1QapGen) repeats information from Genesis.[55]
The Qumran Scrolls, also indicate that Melchizedek was used as a name of the Archangel Michael, interpreted as a heavenly priest; Michael as Melchi-zedek contrast with Belial, who is given the name of Melchi-resha 'king of wickedness'.[56][57] The text of the Epistle to the Hebrews follows this interpretation in stating explicitly that the name in Greek translation (ἑρμηνευόμενος) means βασιλεὺς δικαιοσύνης ('king of righteousness'), omitting translation of the possessive suffix; the same passage interprets Melchizedek's title of king of Salem as translating to βασιλεὺς εἰρήνης 'king of peace', the context being the presentation of Melchizedek's as an eternal priesthood associated with Jesus Christ (ἀφωμοιωμένος δὲ τῷ υἱῷ τοῦ θεοῦ μένει ἱερεὺς εἰς τὸ διηνεκές, 'made like unto the Son of God abideth a priest continually').[58]
