13 Here is a list, by their names and clans, of Ishmael's descendants: The oldest was Nebaioth, followed by Kedar, Adbeel, Mibsam, 14 Mishma, Dumah, Massa, 15 Hadad, Tema, Jetur, Naphish, and Kedemah. 16 These twelve sons of Ishmael became the founders of twelve tribes named after them, listed according to the places they settled and camped.

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.
