13 And these were the names of the sons of Ishmael, by their names, according to their generations: The firstborn of Ishmael, Nebajoth; then Kedar, Adbeel, Mibsam, 14 Mishma, Dumah, Massa, 15 Hadar, Tema, Jetur, Naphish, and Kedemah. 16 These were the sons of Ishmael and these were their names, by their towns and their settlements, twelve princes according to their nations.

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.
