Therefore the king hearkened not unto the people; for the turn of affairs was from the LORD, that he might perform his saying, which the LORD spoke by Ahijah the Shilonite unto Jeroboam the son of Nebat.

Augustine of Hippo
Who can help but tremble at the thought of these judgments of God whereby he accomplishes whatever he pleases even in the hearts of wicked people, while yet rendering to each according to his merits? Solomon’s son, Rehoboam, rejected the salutary counsel of the elders, not to deal harshly with the people, and yielded to the words of men of his own age by replying with threats to those who should have been given a gentle reply. And how did this come about, except by his own will? But as a result of it, the ten tribes of Israel withdrew from him and set up for themselves another king, Jeroboam, that the will of God, who had been angered, might be accomplished, as he had also foretold that it would come to pass. For what does the Scripture say? “And the king condescended not to the people, for the Lord was turned away from him to make good his word, which he had spoken though Ahias, the Silonite, to Jeroboam the son of Nabat.” All this was certainly done by human will, but in such a way that the “turning way” came from the Lord.
