1 Kings 12:19 - Matthew Poole's English Annotations on the Holy Bible

Their revolt is called rebellion, and therefore was sinful, because it was contrary to God's authority, and command of subjection to David, and his seed for ever; from which the people were not freed by God's promise and grant made to Jeroboam, which was but a secret transaction, not yet sufficiently revealed to them, and was not a grant of present and actual possession; but only a promise that God would give it to him in his own time and way, which might have been done, though neither Jeroboam nor the people had used these indirect and evil courses to bring it about, as it befell David upon the same occasion. Besides, the people did not this in compliance with God's counsel, but to gratify their own passions, and get themselves a little ease.
