1 Samuel 31:2-4

2The Philistines were in hot pursuit of Saul and his sons, and they killed his sons Jonathan, Abinadab and Malki-Shua.

3The fighting grew fierce around Saul, and when the archers overtook him, they wounded him critically.

4Saul said to his armor-bearer, “Draw your sword and run me through, or these uncircumcised fellows will come and run me through and abuse me.” But his armor-bearer was terrified and would not do it; so Saul took his own sword and fell on it.
