So Saul died, and his three sons, and his armourbearer, and all his men, that same day together.

Jamieson-Fausset-Brown Bible Commentary

6. So Saul died-(see on [255]1Ch 10:13; [256]Ho 13:11).

and his three sons-The influence of a directing Providence is evidently to be traced in permitting the death of Saul's three eldest and most energetic sons, particularly that of Jonathan, for whom, had he survived his father, a strong party would undoubtedly have risen and thus obstructed the path of David to the throne.

and all his men, that same day together-his servants or bodyguard (1Ch 10:6).

Matthew Henry's Concise Commentary

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.
