Verse 19

And Hadad smote all the children of Midian and the children of the east with the edge of the sword, and Hadad at that time delivered Moab from the hand of Midian, and those that remained of Midian and of the children of the east fled before Hadad and his army, and Hadad pursued them to their land, and smote them with a very heavy slaughter, and the slain fell in the road.
