1 Chronicles 10:5-7

New Living Translation

⁵ When his armor bearer realized that Saul was dead, he fell on his own sword and died. ⁶ So Saul and his three sons died there together, bringing his dynasty to an end.

⁷ When all the Israelites in the Jezreel Valley saw that their army had fled and that Saul and his sons were dead, they abandoned their towns and fled. So the Philistines moved in and occupied their towns.
