28 Then the man of God went to the king of Israel and said, "This is what the Lord says: The Arameans have said, 'The Lord is a god of the hills and not of the plains.' So I will defeat this vast army for you. Then you will know that I am the Lord ."
Matthew Henry's Commentary on 1 Kings 20:28
Commentary on 1 Kings 20:22-30
(Read 1 Kings 20:22-30)
Those about Benhadad advised him to change his ground. They take it for granted that it was not Israel, but Israel's gods, that beat them; but they speak very ignorantly of Jehovah. They supposed that Israel had many gods, to whom they ascribed limited power within a certain district; thus vain were the Gentiles in their imaginations concerning God. The greatest wisdom in worldly concerns is often united with the most contemptible folly in the things of God.
