Melchizedek or Malki-tzédek (מלכי־צדק "My king is righteous", Standard Hebrew Malki-ẓédeq / Malki-ẓádeq, Tiberian Hebrew Malkî-ṣéḏeq / Malkî-ṣāḏeq), sometimes written Melchisedec, Melchisedech or Melchisedek, is a character in the Bible who appeared in Genesis to the patriarch Abraham. He is called "king of Salem (believed to be ancient Jerusalem)" and "priest of the most high God" in Genesis 14:18.
Reference to Melchizedek is brief in the Old Testament. Melchizedek first appears bringing bread and wine to Abraham (then Abram) after his victory (described in Genesis 14) over the four kings who had besieged Sodom and Gomorrah and had taken his nephew Lot prisoner. In return, Abraham gives Melchizedek a tithe of the bounty that he took in battle:
Psalm 110:4 names Melchizedek as representative of the priestly line through which a future king of Israel's Davidic line was ordained. The future king -- in Christian belief, Jesus Christ -- is referred to as a "priest for ever after the order of Melchizedek".
Some rabbinic scholars identify Melchizedek with Noah's son Shem. The account of Melchizedek given in the Dead Sea Scrolls has also divided scholars into two camps, one that touts his existence as a mortal man and another that identifies him with the archangel Michael.
Hebrews 7:3 in the New Testament refers to Melchizedek as a king "without father or mother or genealogy", a reference which some Christians take as referring to Melchizedek's true nature as an angel or even as Jesus himself, appearing thousands of years before his earthly incarnation.
According to the tradition of the Church of Jesus Christ of Latter-day Saints (LDS), Melchizedek's blessing of Abraham at Salem is a priesthood authority whose keys were restored to Joseph Smith along with the keys of Aaron's priesthood. See Melchizedek Priesthood and Aaronic Priesthood.
