Genesis 14:19-24

19 blessed him, and said, "May the Most High God, who made heaven and earth, bless Abram!
20 May the Most High God, who gave you victory over your enemies, be praised!" And Abram gave Melchizedek a tenth of all the loot he had recovered.
21 The king of Sodom said to Abram, "Keep the loot, but give me back all my people."
22 Abram answered, "I solemnly swear before the Lord, the Most High God, Maker of heaven and earth,
23 that I will not keep anything of yours, not even a thread or a sandal strap. Then you can never say, "I am the one who made Abram rich.'
24 I will take nothing for myself. I will accept only what my men have used. But let my allies, Aner, Eshcol, and Mamre, take their share."
