Then Melchizedek king of Salem brought out bread and wine—since he was priest of God Most High— / and he blessed Abram and said: “Blessed be Abram by God Most High, Creator of heaven and earth, / and blessed be God Most High, who has delivered your enemies into your hand.” Then Abram gave Melchizedek a tenth of everything.
