Genesis 14:22

20Blessed be God Most High, who has delivered your enemies into your hand.” Abram gave him a tenth of all.

21The king of Sodom said to Abram, “Give me the people, and take the goods for yourself.”

22Abram said to the king of Sodom, “I have lifted up my hand to the LORD, God Most High, possessor of heaven and earth,

23that I will not take a thread nor a sandal strap nor anything that is yours, lest you should say, ‘I have made Abram rich.’

24I will accept nothing from you except that which the young men have eaten, and the portion of the men who went with me: Aner, Eshcol, and Mamre. Let them take their portion.”
