And Jehoash the son of Jehoahaz took again out of the hand of Benhadad the son of Hazael the cities, which he had taken out of the hand of Jehoahaz his father by war. Three times did Joash beat him, and recovered the cities of Israel. Three times did Joash beat him - The particulars of these battles we have not; but these three victories were according to the prediction of Elisha, 2 Kings 13:19. That these victories were very decisive we learn from their fruits, for Joash took from the Syrians the cities which Hazael had taken from Israel: viz., Gilead, the possessions of Reuben, Gad, and the half-tribe of Manasseh, and the country of Bashan; see 2 Kings 10:33.
Thus God accomplished his word of judgment, and his word of mercy. The Syrians found themselves to be but men, and the Israelites found they could do nothing without God. In the dispensations of his justice and mercy, God has ever in view, not only the comfort, support, and salvation of his followers, but also the conviction and salvation of his enemies; and by his judgments many of these have been awakened out of their sleep, turned to God, learned righteousness, and finally become as eminent for their obedience, as they were before for their rebellion.
