1 Samuel 31:1-4

New International Version - UK

Saul takes his life

31 Now the Philistines fought against Israel; the Israelites fled before them, and many fell dead on Mount Gilboa. 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 critically.

⁴ Saul said to his armour-bearer, ‘Draw your sword and run me through, or these uncircumcised fellows will come and run me through and abuse me.’

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