Genesis 14:18-21

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] The king of Sodom said to Abram, “Give me the people and keep the goods (spoils of battle) for yourself.”
