4 Saul said to his weapon bearer, "Draw your sword and put me out of my misery, lest these pagan pigs come and make a game out of killing me." 5 When the weapon bearer saw that Saul was dead, he too fell on his sword and died with him. 6 So Saul, his three sons, and his weapon bearer - the men closest to him - died together that day.

Commentary on 1 Samuel 31:1-7
(Read 1 Samuel 31:1-7)
We cannot judge of the spiritual or eternal state of any by the manner of their death; for in that, there is one event to the righteous and to the wicked. Saul, when sorely wounded, and unable to resist or to flee, expressed no concern about his never-dying soul; but only desired that the Philistines might not insult over him, or put him to pain, and he became his own murderer. As it is the grand deceit of the devil, to persuade sinners, under great difficulties, to fly to this last act of desperation, it is well to fortify the mind against it, by a serious consideration of its sinfulness before God, and its miserable consequences in society. But our security is not in ourselves. Let us seek protection from Him who keepeth Israel. Let us watch and pray; and take unto us the whole armour of God, that we may be able to withstand in the evil day, and having done all, to stand.
