1 Chronicles 10:13 Meaning and Commentary

1 Chronicles 10:13

So Saul died for his transgression
(See Gill on 1 Samuel 31:13) A violent and dishonourable death, which was suffered on account of the sins he was guilty of:

one was, which he committed against the Lord, even against the word of
the Lord, which he kept not;
both in not staying for Samuel the time appointed, and by sparing the Amalekites whom he was bid to destroy, ( 1 Samuel 13:13 1 Samuel 13:14 ) ( 1 Samuel 15:3 1 Samuel 15:9 )

and also for asking counsel of one that had a familiar spirit, to
inquire of it;
what he should do with respect to engaging in battle with the Philistines, ( 1 Samuel 28:8 1 Samuel 28:15 ) which to do was contrary to an express command of God, ( Leviticus 19:31 ) .

12 All the valiant men of them arose, and took the bodies of Saul and of his sons, and brought them to Jabes, and buried their bones under the oak that was in Jabes, and they fasted seven days.

13 So Saul died for his iniquities, because he transgressed the commandment of the Lord, which he had commanded, and kept it not: and moreover consulted also a witch,

14 And trusted not in the Lord: therefore he slew him, and transferred his kingdom to David the son of Isai.
