Genesis 14:21-24

The king of Sodom said to Abram, “You may keep all these things for yourself. Just give me my people who were captured.” But Abram said to the king of Sodom, “I make a promise to the LORD, the God Most High, who made heaven and earth. I promise that I will not keep anything that is yours. I will not keep even a thread or a sandal strap so that you cannot say, ‘I made Abram rich.’ I will keep nothing but the food my young men have eaten. But give Aner, Eshcol, and Mamre their share of what we won, because they went with me into battle.”
