Charles Ellicott Commentary 2 Chronicles 10:15

"So the king hearkened not unto the people; for it was brought about of God, that Jehovah might establish his word, which he spake by Ahijah the Shilonite to Jeroboam the son of Nebat." — 2 Chronicles 10:15 (ASV)

The cause was from God. — It was brought about by God. Literally, it was a turn or turning-point (of events) from God. The word n’sibbah is equivalent to sibbah of Kings. Both are isolated in the Old Testament. The latter is the common word for “cause” in Rabbinic, as sibbath sibbôth — causa causarum.

That the Lord might perform his word. —The chronicler does not deviate from the text of Kings here, although he has not mentioned Ahijah’s prophecy to Jeroboam before. (Compare 2 Chronicles 9:29.)
