Genesis 14:17-20

After Abram returned from defeating Chedorlaomer and the kings who were with him, the king of Sodom went out to meet him in the Valley of Shaveh (that is, the King’s Valley ). Then Melchizedek, king of Salem, brought out bread and wine; he was a priest to God Most High. He blessed him and said: Abram is blessed by God Most High, Creator of heaven and earth, and I give praise to God Most High who has handed over your enemies to you. And Abram gave him a tenth of everything.
