1 Kings 20:23
And the servants of the king of Syria said unto him, Their gods are gods of the hills; therefore they were stronger than we; but let us fight against them in the plain, and surely we shall be stronger than they. And the servants of the king of Syria said unto him, Their gods are gods of the hills; therefore they were stronger than we; but let us fight against them in the plain, and surely we shall be stronger than they.
1 Kings 12 to 22 give the history of the two separate kingdoms of Judah and Israel for about eighty years from the revolt of the ten tribes to the death of Jehoshaphat, tracing the reigns of several kings of both Judah and Israel. The verse belongs to the account of the Syrians' second attack on Israel, in which Ben-hadad, king of Syria, was defeated. In that battle the Syrians filled the country while Israel's army looked like two small flocks of kids, yet Israel defeated them and 100,000 Syrian footmen fell.
The servants' words express the mistaken belief that Israel's God was powerful only in the hills and that Syria would surely defeat Israel in the plain. God gave Israel victory over the Syrian army to show Ahab that the victory came from Jehovah, another effort by God to win over the weak Ahab.
