1 Chronicles 1:28-32

The sons of Abraham; Isaac, and Ishmael.

These are their generations: The firstborn of Ishmael, Nebaioth; then Kedar, and Adbeel, and Mibsam,

Mishma, and Dumah, Massa, Hadad, and Tema,

Jetur, Naphish, and Kedemah. These are the sons of Ishmael.

Now the sons of Keturah, Abraham’s concubine: she bare Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah. And the sons of Jokshan; Sheba, and Dedan.
