1 Chronicles 5:8-10

Young's Literal Translation

⁸ and Bela son of Azaz, son of Shema, son of Joel -- he is dwelling in Aroer, even unto Nebo and Baal-Meon;

⁹ and at the east he dwelt even unto the entering in of the wilderness, even from the river Phrat, for their cattle were multiplied in the land of Gilead.

¹⁰ And in the days of Saul they have made war with the Hagarites, who fall by their hand, and they dwell in their tents over all the face of the east of Gilead.
