1 Chronicles 10:3-5

Amplified Bible

³ The battle became heavy against Saul, and the archers found him; and he was [mortally] wounded by the archers. ⁴ Then Saul said to his armor bearer, “Draw your sword and run me through with it, otherwise these uncircumcised [Philistines] will come and abuse and humiliate me.” But his armor bearer would not, for he was terrified. So Saul took his own sword and fell on it. ⁵ When his armor bearer saw that Saul was dead, he also fell on his sword and died.
