Genesis 14:18-20 (NKJV)

18 Then Melchizedek king of Salem brought out bread and wine; he was the priest of God Most High.
19 And he blessed him and said:

“Blessed be Abram of God Most High,
Possessor of heaven and earth;
20 And blessed be God Most High,
Who has delivered your enemies into your hand.”
And he gave him a tithe of all.
