1 Chronicles 10:2-4

New International Version

² The Philistines were in hot pursuit of Saul and his sons, and they killed his sons Jonathan, Abinadab and Malki-Shua. ³ The fighting grew fierce around Saul, and when the archers overtook him, they wounded him.

⁴ Saul said to his armor-bearer, “Draw your sword and run me through, or these uncircumcised fellows will come and abuse me.”

But his armor-bearer was terrified and would not do it; so Saul took his own sword and fell on it.
