1 Chronicles 10:2-6

The Philistines closely pursued Saul and his sons, and the Philistines struck down Jonathan, Abinadab and Malchi-shua, the sons of Saul. The battle became heavy against Saul, and the archers overtook him; and he was wounded by the archers. Then Saul said to his armor bearer, “Draw your sword and thrust me through with it, otherwise these uncircumcised will come and abuse me.” But his armor bearer would not, for he was greatly afraid. Therefore Saul took his sword and fell on it. When his armor bearer saw that Saul was dead, he likewise fell on his sword and died. Thus Saul died with his three sons, and all those of his house died together.
