So Saul died, and his three sons, and all his house died together.

Wesley's Notes

10:6 His house - All his children, then present with him, namely, his three sons, for Ishbosheth and Mephiboshieth were not slain.

Jamieson-Fausset-Brown Bible Commentary

6. Saul died, and his three sons, and all his house-his sons and courtiers who were there engaged in the battle. But it appears that Ish-bosheth and Mephibosheth were kept at Gibeah on account of their youth.

Matthew Henry's Concise Commentary

10:1-14 The death of Saul. - The design chiefly in view in these books of the Chronicles, appears to be to preserve the records of the house of David. Therefore the writer repeats not the history of Saul's reign, but only of his death, by which a way was made for David to the throne. And from the ruin of Saul, we may learn, 1. That the sin of sinners will certainly find them out, sooner or later; Saul died for his transgression. 2. That no man's greatness can exempt him from the judgments of God. 3. Disobedience is a killing thing. Saul died for not keeping the word of the Lord. May be delivered from unbelief, impatience, and despair. By waiting on the Lord we shall obtain a kingdom that cannot be moved.
