For his transgression - Compare 1-Chronicles 9:1. The "transgression" intended is probably the disobedience with respect to Amalek, recorded in 1-Samuel 15:1-9 (compare 1-Samuel 28:17-18).
Saul died for his transgression - See the concluding observations on the first book of Samuel (1-Samuel 31:13 (note)).
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.
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 which to do was contrary to an express command of God, Leviticus 19:31.
Saul died for his transgression which he committed against the Lord--in having spared the king of the Amalekites and taken the flocks of the people as spoils [1-Samuel 15:9], as well as in having consulted a pythoness [1-Samuel 28:7]. Both of these acts were great sins--the first as a violation of God's express and positive command [1-Samuel 15:3], and the second as contrary to a well-known statute of the kingdom (Leviticus 19:31).
The word - Against God's express command: which is a great aggravation of any sin. Familiar spirit - Which also was contrary to a manifest command, Leviticus 19:31.
