8And Bela the son of Azaz, the son of Shema, the son of Joel, who dwelt in Aroer, even to Nebo and Baalmeon:1

9And eastward he inhabited to 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 Hagarites, who fell by their hand: and they dwelt in their tents throughout all the east land of Gilead.2
