Genesis 14:18-20

14:18 Melchizedek king of Salem brought out bread and wine. (Now he was the priest of the Most High God.) 14:19 He blessed Abram, saying,

“Blessed be Abram by the Most High God,

Creator of heaven and earth.

14:20 Worthy of praise is the Most High God,

who delivered your enemies into your hand.”

Abram gave Melchizedek a tenth of everything.
