1 Samuel 31:4 Then Saul said to his armor bearer, "Draw your sword and pierce me through with it, otherwise these uncircumcised will come and pierce me through and make sport of me." But his armor bearer would not, for he was greatly afraid. So Saul took his sword and fell on it.

1 Samuel 31:5 When his armor bearer saw that Saul was dead, he also fell on his sword and died with him.

2 Samuel 17:23 Now when Ahithophel saw that his counsel was not followed, he saddled his donkey and arose and went to his home, to his city, and set his house in order, and strangled himself; thus he died and was buried in the grave of his father. (NASB ©1995)
