12 Now these are the generations of Ishmael, the son of Abraham, whose mother was Hagar the Egyptian, the servant of Sarah: 13 These are the names of the sons of Ishmael by their generations: Ishmael's first son was Nebaioth; then Kedar and Adbeel and Mibsam 14 And Mishma and Dumah and Massa, 15 Hadad and Tema, Jetur, Naphish, and Kedemah: 16 These are the sons of Ishmael, and these are their names in their towns and their tent-circles; twelve chiefs with their peoples. 17 And the years of Ishmael's life were a hundred and thirty-seven: and he came to his end, and was put to rest with his people. 18 And their country was from Havilah to Shur which is east of Egypt: they took their place to the east of all their brothers.

(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.
