4 Then Saul said to the servant who had the care of his arms, Take out your sword and put it through me, before these men without circumcision come and make sport of me. But his servant, full of fear, would not do so. Then Saul took out his sword, and falling on it, put an end to himself. 5 And when his servant saw that Saul was dead, he did the same, and was united with him in death. 6 So death overtook Saul and his three sons and his servant on the same day.
Matthew Henry's Commentary on 1 Samuel 31:4-6
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.
