And the rest of the acts of Jeroboam, how he warred, and how he reigned, behold, they are written in the book of the chronicles of the kings of Israel.

Wesley's Notes

14:19 The chronicles - not that canonical book of chronicles; for that was written long after this book: but a book of civil records, the annals, wherein all remarkable passages were recorded by the king's command from day to day; out of which the sacred penman by the direction of God's spirit, took those passages which were most useful for God's honour, and mens edification.

Jamieson-Fausset-Brown Bible Commentary

19. the rest of the acts of Jeroboam-None of the threatenings denounced against this family produced any change in his policy or government.

Matthew Henry's Concise Commentary

14:7-20 Whether we keep an account of God's mercies to us or not, he does; and he will set them in order before us, if we are ungrateful, to our greater confusion. Ahijah foretells the speedy death of the child then sick, in mercy to him. He only in the house of Jeroboam had affection for the true worship of God, and disliked the worship of the calves. To show the power and sovereignty of his grace, God saves some out of the worst families, in whom there is some good thing towards the Lord God of Israel. The righteous are removed from the evil to come in this world, to the good to come in a better world. It is often a bad sign for a family, when the best in it are buried out of it. Yet their death never can be a loss to themselves. It was a present affliction to the family and kingdom, by which both ought to have been instructed. God also tells the judgments which should come upon the people of Israel, for conforming to the worship Jeroboam established. After they left the house of David, the government never continued long in one family, but one undermined and destroyed another. Families and kingdoms are ruined by sin. If great men do wickedly, they draw many others, both into the guilt and punishment. The condemnation of those will be severest, who must answer, not only for their own sins, but for sins others have been drawn into, and kept in, by them.
