1 Chronicles 10:7

When all the Israelites in the valley saw that the army had fled and that Saul and his sons had died, they abandoned their cities and ran away. So the Philistines came and occupied their cities.

And when all the men of Israel that were in the valley saw that they fled, and that Saul and his sons were dead, then they forsook their cities, and fled: and the Philistines came and dwelt in them.
