Book of Jubilees 13:29
Abram said to him: ‘I lift my hands to the most high God (to show that) I will not take anything of yours — not a thread or sandal thongs, so that you may not say: «I have made Abram rich» — excepting only what the young men have eaten and the share of the men who went with me: Awnan, Eschol, and Mamre. These will take their share’.
