Genesis 14:21-24

The king of Sodom said to Abram, “Give me the people and keep the goods for yourself.” But Abram said to the king of Sodom, “With raised hand I have sworn an oath to the LORD, God Most High, Creator of heaven and earth, that I will accept nothing belonging to you, not even a thread or the strap of a sandal, so that you will never be able to say, ‘I made Abram rich.’ I will accept nothing but what my men have eaten and the share that belongs to the men who went with me—to Aner, Eshkol and Mamre. Let them have their share.”
