1 Kings 20:34

Ben-hadad, secure of his life, suggests terms of peace as the price of his freedom. He will restore to Ahab the Israelite cities taken from Omri by his father, among which Ramoth Gilead was probably the most important 1 Kings 22:3; and he will allow Ahab the privilege of making for himself “streets,” or rather squares, in Damascus, a privilege which his own father had possessed with respect to Samaria. Commercial advantages, rather than any other, were probably sought by this arrangement.

So he made a covenant with him ... - Ahab, without “inquiring of the Lord,” at once agreed to the terms offered; and, without even taking any security for their due observance, allowed the Syrian monarch to depart. Considered politically, the act was one of culpable carelessness and imprudence. Ben-hadad did not regard himself as bound by the terms of a covenant made when he was a prisoner - as his after conduct shows 1 Kings 22:3. Ahab’s conduct was even more unjustifiable in one who held his crown under a theocracy. “Inquiry at the word of the Lord” was still possible in Israel 1Ki 22:5, 1 Kings 22:8, and would seem to have been the course that ordinary gratitude might have suggested.
