Genesis 25:15

And these are the names of the sons of Ishmael, by their names, according to their generations: the firstborn of Ishmael, Nebajoth; and Kedar, and Adbeel, and Mibsam,

And Mishma, and Dumah, and Massa,

These are the sons of Ishmael, and these are their names, by their towns, and by their castles; twelve princes according to their nations.

And these are the years of the life of Ishmael, an hundred and thirty and seven years: and he gave up the ghost and died; and was gathered unto his people.
