1 Samuel 31:2-4

2The Philistines pressed hard after Saul and his sons, and the Philistines struck down Jonathan, Abinadab and Malchishua, the sons of Saul.

3When the battle intensified against Saul, the archers hit him, so he was severely wounded by the archers.

4Then Saul said to his armor-bearer, “Draw your sword and thrust me through with it, or else these uncircumcised will come and thrust me through after torturing me.” But his armor-bearer refused, for he was too afraid. So Saul took the sword and fell on it.
