American Standard Version

⁵ And when his armorbearer saw that Saul was dead, he likewise fell upon his sword, and died. ⁶ So Saul died, and his three sons; and all his house died together.

⁷ And when all the men of Israel that were in the valley saw that they fled, and that Saul and his sons were dead, they forsook their cities, and fled; and the Philistines came and dwelt in them.
