1 Chronicles 5:7-10

7And his kinsmen by their clans, when the genealogy of their generations was recorded: the chief, Jeiel, and Zechariah,

8and Bela the son of Azaz, son of Shema, son of Joel, who lived in Aroer, as far as Nebo and Baal-meon.

9He also lived to the east as far as the entrance of the desert this side of the Euphrates, because their livestock had multiplied in the land of Gilead.

10And in the days of Saul they waged war against the Hagrites, who fell into their hand. And they lived in their tents throughout all the region east of Gilead.
