Genesis 25:12-16

12Now these are the records of the descendants of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s maid, bore to Abraham;

13and these are the names of the [twelve] sons of Ishmael, named in the order of their births: Nebaioth, the firstborn of Ishmael, and Kedar, Adbeel, Mibsam,

14Mishma, Dumah, Massa,

15Hadad, Tema, Jetur, Naphish, and Kedemah.

16These are the sons of Ishmael and these are their names, by their settlements, and by their encampments (sheepfolds); twelve princes (sheiks) according to their tribes.
