1 Samuel 31:4-5

41Then Saul said to his armor bearer, “Draw your sword and pierce me through with it, otherwise 2these uncircumcised will come and pierce me through and make sport of me.” But his armor bearer would not, for he was greatly afraid. 3So Saul took his sword and fell on it.

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