1 Kings 11:34 - Joseph Benson’s Commentary on the Old and New Testaments

I will not take the whole kingdom out of his hands Solomon held even the ten tribes as long as he lived. But I will make him prince all the days of his life This was an admonition to Jeroboam not to molest Solomon in his life-time, by raising a rebellion against him; and also to walk in God's ways as David did, and not fall into idolatry; for which sin God resolved to punish Solomon so severely as to rend the greatest part of his kingdom from his posterity. For David my servant's sake Not for his own sake; he had forfeited his crown to the justice of God; but for his father's sake. “Children that do not tread in their parents' steps,” says Henry, “yet often fare the better in this world for their good parents' piety.”
