Isaiah 11:13-14

Then the jealousy of Ephraim will depart, And those who harass Judah will be cut off; Ephraim will not be jealous of Judah, And Judah will not harass Ephraim. Ephraim and Judah will [unite and] swoop down on the slopes of the Philistines toward the west; Together they will plunder the sons (Arabs) of the east. They will possess Edom and Moab, And the sons of Ammon will be subject to them.
