1 Samuel 31:4-5

He said to the young man carrying his weapons, “Draw your sword and kill me, so that these godless Philistines won't gloat over me and kill me.” But the young man was too terrified to do it. So Saul took his own sword and threw himself on it. The young man saw that Saul was dead, so he too threw himself on his own sword and died with Saul.
