1 Kings 20:6
Yet I will send my servants unto thee to morrow about this time, and they shall search thine house, and the houses of thy servants; and it shall be, that whatsoever is pleasant in thine eyes, they shall put it in their hand, and take it away.
Ben-hadad threatened Ahab that about that time on the morrow he would send his servants to search his house and the houses of his servants and to lay hands on and carry off whatever was pleasant and desirable in his eyes. The threat belonged to the boastful attack of the Syrian king upon Israel in his siege of Samaria. That conflict ended with the forces of Israel defeating the Syrians and Ben-hadad fleeing in defeat.
The boastful attack was met by warning and reproof through a prophet. God granted Ahab a great victory over the Syrians so that he would know the victory came from Jehovah. In this defeat of Ben-hadad, God was making another effort to win the weak Ahab to Himself.
