1 Samuel 31:5-7

New Catholic Bible

⁵ When his armor-bearer saw that Saul was dead, he, too, fell upon his sword and died with him.

⁶ So Saul and his three sons and his armor-bearer and all of his men died together on the same day. ⁷ When the Israelites on the other side of the valley and those on the other side of the Jordan saw that the Israelites had fled and that Saul and his sons were dead, they abandoned the cities, and the Philistines came and occupied them.
