1 Chronicles 5:8

6and Beerah his son, whom Tilgath Pilneser king of Assyria carried away captive. He was prince of the Reubenites.

7His brothers by their families, when the genealogy of their generations was listed: the chief, Jeiel, and Zechariah,

8and Bela the son of Azaz, the son of Shema, the son of Joel, who lived in Aroer, even to Nebo and Baal Meon;

9and he lived eastward even to the entrance of the wilderness from the river Euphrates, because their livestock were multiplied in the land of Gilead.

10In the days of Saul, they made war with the Hagrites, who fell by their hand; and they lived in their tents throughout all the land east of Gilead.
