1 Kings 15:6

Which was said 1 Kings 14:30, and may be here repeated, to signify the cause and original of the war between Abijam and Jeroboam, which is implied here, and particularly described 2Ch 13. Abijam continued the war which Rehoboam had begun, and pushed it on to a decisive battle. But the place may be thus rendered, Yet there was war, &c., i.e. although God was pleased to show so much respect to David, as for his sake to continue the succession to the kingdom in his posterity, yet he thought fit to manifest his displeasure against David's successors for their sins, and to mix their honour and happiness with wars and troubles.
