1 Chronicles 5:7-10

7And his brethren by their families, when the genealogy of their generations was reckoned; 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 Baal-meon:

9and eastward he dwelt even 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 Hagrites, who fell by their hand: and they dwelt in their tents throughout all the land east of Gilead.
