12 These are the descendants of Ishmael, Abraham's son, whom Hagar the Egyptian, Sarah's slave-girl, bore to Abraham. 13 These are the names of the sons of Ishmael, named in the order of their birth: Nebaioth, the firstborn of Ishmael; and Kedar, Adbeel, Mibsam, 14 Mishma, Dumah, Massa, 15 Hadad, 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 tribes. 17 (This is the length of the life of Ishmael, one hundred thirty-seven years; he breathed his last and died, and was gathered to his people.)

(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.
