Jubilees 13:29

And Abram said unto him: 'I lift up my hands to the Most High God, that from a thread to a shoe-latchet I shall not take aught that is thine lest thou shouldst say, I have made Abram rich; save only what the young men have eaten, and the portion of the men who went with me -Aner, Eschol, and Mamre. These shall take their portion.'
