Genesis 14:14-20

When Abram heard that his nephew [Lot] had been captured, he armed and led out his trained men, born in his own house, [numbering] three hundred and eighteen, and went in pursuit as far [north] as Dan. He divided his forces against them by night, he and his servants, and attacked and defeated them, and pursued them as far as Hobah, which is north of Damascus. And he brought back all the goods, and also brought back his nephew Lot and his possessions, and also the women, and the people. Then after Abram’s return from the defeat (slaughter) of Chedorlaomer and the kings who were with him, the king of Sodom went out to meet him at the Valley of Shaveh (that is, the King’s Valley). Melchizedek king of Salem (ancient Jerusalem) brought out bread and wine [for them]; he was the priest of God Most High. And Melchizedek blessed Abram and said, “Blessed (joyful, favored) be Abram by God Most High, Creator and Possessor of heaven and earth; And blessed, praised, and glorified be God Most High, Who has given your enemies into your hand.” And Abram gave him a tenth of all [the treasure he had taken in battle]. [Heb 7:1-10]
