1 Kings 15:16

And there was war between Asa and Baasha king of Israel all their days.

There was war between Asa and Baasha king of Israel all their days. Asa enjoyed a ten years' peace after Jeroboam's defeat by Abijam, and this interval was wisely and energetically spent in making internal reforms, as well as increasing the means of national defense (2 Chronicles 14:1). In the 15th year of his reign, however, the king of Israel commenced hostilities against him, and invaded his kingdom.
