1 Chronicles 5:8 KJV

6Beerah his son, whom Tilgathpilneser king of Assyria carried away captive: he was prince of the Reubenites.

7And his brethren by their families, when the genealogy of their generations was reckoned, were the chief, Jeiel, and Zechariah,

8And Bela the son of Azaz, the son of Shema, the son of Joel, who dwelt in Aroer, even unto Nebo and Baalmeon:

9And eastward he inhabited unto the entering in of the wilderness from the river Euphrates: because their cattle were multiplied in the land of Gilead.

10And in the days of Saul they made war with the Hagarites, who fell by their hand: and they dwelt in their tents throughout all the east land of Gilead.
