Genesis 25:16-18
16 These were the sons of Ishmael, and these are the names of the twelve tribal rulers according to their settlements and camps.
17 Altogether, Ishmael lived a hundred and thirty-seven years. He breathed his last and died, and he was gathered to his people.
18 His descendants settled in the area from Havilah to Shur, near the border of Egypt, as you go toward Asshur. And they lived in hostility toward all their brothers.
