A fugitive brought the news to Abram the Hebrew, who was dwelling at the terebinths of Mamre the Amorite, kinsman of Eshkol and Aner, these being Abram’s allies. When Abram heard that his kinsman had been taken captive, he mustered his retainers, born into his household, numbering three hundred and eighteen, and went in pursuit as far as Dan. At night, he and his servants deployed against them and defeated them; and he pursued them as far as Hobah, which is north of Damascus. He brought back all the possessions; he also brought back his kinsman Lot and his possessions, and the women and the rest of the people.
When he returned from defeating Chedorlaomer and the kings with him, the king of Sodom came out to meet him in the Valley of Shaveh, which is the Valley of the King. And King Melchizedek of Salem brought out bread and wine; he was a priest of God Most High. He blessed him, saying,
“Blessed be Abram of God Most High,
Creator of heaven and earth.
And blessed be God Most High,
Who has delivered your foes into your hand.”
And [Abram] gave him a tenth of everything. Genesis 15/13-20 Tanakh JPS 1985.
King Melchizedek of Salem which is Jerusalem on G-d’s Holy Mount Zion. Canaanites were the inhabitants when the land was allotted to the tribe of Benjamin though the tribe never fully defeated them or completely removed them from Jerusalem.
King Melchizedek was a priest of G-d Most High and he blessed Abram of G-d Most High and he blessed G-d Most High for delivering the foes of Abram into his hands.
The land G-d promised Abraham was the land of Canaan. The Canaanites already knew the G-d of Abraham who is the G-d of all creation. G-d selected the land of Canaan and chose Jerusalem before He declared Abram Hebrew.
A King in Jerusalem who is also a priest of the G-d of Abraham has not been seen since Melchizedek and David.
