1 Chronicles 10:14

And inquired not of the Lord
For though he did inquire in some sense in an external, careless, and hypocritical manner, yet not done seriously, sincerely, and heartily, nor with constancy; it was accounted as if he inquired not at all, ( 1 Samuel 28:6 ) the Targum adds another reason of his death, because he killed the priests of Nob; but that is not in the text:

therefore he slew him;
or suffered him to be slain:

and turned the kingdom unto David the son of Jesse;
translated the kingdom of Israel out of Saul's family, upon his death, into Jesse's, even unto David; for the sake of which observation this short account is given of the last end of Saul.
