1 Samuel 31:4-5

41Then Saul said to his armor bearer, “Draw your sword and pierce me through with it, otherwise 2these uncircumcised Philistines will come and pierce me through, and abuse me.” But his armor bearer was unwilling, because he was very fearful. 3So Saul took 4his sword and fell on it.

5When his armor bearer saw that Saul was dead, he also fell on his sword and died with him.
