12 Now these are the generations of Ishmael, Abraham's son, whom Hagar the Egyptian, Sarah's handmaid, bare unto Abraham. 13 And these are the names of the sons of Ishmael, by their names, according to their generations: the first-born of Ishmael, Nebaioth, and Kedar, and Adbeel, and Mibsam, 14 and Mishma, and Dumah, and Massa, 15 Hadad, and Tema, Jetur, Naphish, and Kedemah. 16 These are the sons of Ishmael, and these are their names, by their villages, and by their encampments. Twelve princes according to their nations. 17 And these are the years of the life of Ishmael, a hundred and thirty and seven years. And he gave up the ghost and died, and was gathered unto his people. 18 And they dwelt from Havilah unto Shur that is before Egypt, as thou goest toward Assyria. He abode over against all his brethren.

Commentary on Genesis 25:11-18
(Read Genesis 25:11-18)
Ishmael had twelve sons, whose families became distinct tribes. They peopled a very large country that lay between Egypt and Assyria, called Arabia. The number and strength of this family were the fruit of the promise, made to Hagar and to Abraham, concerning Ishmael.
