1 Chronicles 10:4-6

Then Saul said to his armor-bearer, “Draw your sword and thrust me through with it, lest these uncircumcised come and mistreat me.” But his armor-bearer would not, for he feared greatly. Therefore Saul took his own sword and fell upon it. And when his armor-bearer saw that Saul was dead, he also fell upon his sword and died. Thus Saul died; he and his three sons and all his house died together.
