13 and these 'are' the names of the sons of Ishmael, by their names, according to their births: first-born of Ishmael, Nebajoth; and Kedar, and Adbeel, and Mibsam, 14 and Mishma, and Dumah, and Massa, 15 Hadar, and Tema, Jetur, Naphish, and Kedemah: 16 these are sons of Ishmael, and these their names, by their villages, and by their towers; twelve princes according to their peoples.

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.
