1 Chronicles 10:1-3

Now the Philistines fought against Israel, and the men of Israel fled from the Philistines but fell fatally wounded on Mount Gilboa.

And the Philistines also overtook Saul and his sons, and the Philistines killed Jonathan, Abinadab, and Malchi-shua, the sons of Saul.

The battle became severe against Saul, and the archers found him; and he was wounded by the archers.
