1 Samuel 31:4-6

New Catholic Bible

⁴ Saul said to his armor-bearer, “Draw your sword and thrust it through me, lest these uncircumcised come and thrust me through and abuse me.” But the armor-bearer would not do this for he was terrified. Saul, therefore, took his sword and fell upon it. ⁵ When his armor-bearer saw that Saul was dead, he, too, fell upon his sword and died with him.

⁶ So Saul and his three sons and his armor-bearer and all of his men died together on the same day.
