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 entrance 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.
