The close alliance between the two kingdoms still subsisted. Jehoram therefore sends confidently to make the same request with respect to Moab that his father had made two years before with respect to Syria (marginal reference). Jehoshaphat consented at once, notwithstanding that his former compliance had drawn upon him the rebuke of a prophet 2 Chronicles 19:2. Perhaps Jehoram’s removal of the Baal-worship 2 Kings 3:2 weighed with him. He had himself been attacked by the Moabites in the preceding year; and though the attempt had failed, Jehoshaphat would feel that it might be renewed, and that it was important to seize the opportunity of weakening his enemy which now offered itself.
