And when the men of Israel that were on the other side of the valley, and they that were on the other side Jordan, saw that the men of Israel fled, and that Saul and his sons were dead, they forsook the cities, and fled; and the Philistines came and dwelt in them. The men of Israel that were on the other side of the valley - They appear to have been panic-struck, and therefore fled as far as they could out of the reach of the Philistines. As the Philistines possessed Beth-shan, situated near to Jordan, the people on the other side of that river, fearing for their safety, fled also.
