1 Kings 20:21-25

And the king of Israel went out, and smote the horses and chariots, and slew the Syrians with a great slaughter.

And the prophet came to the king of Israel, and said unto him, Go, strengthen thyself, and mark, and see what thou doest: for at the return of the year the king of Syria will come up against thee.

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 do this thing, Take the kings away, every man out of his place, and put captains in their rooms:

And number thee an army, like the army that thou hast lost, horse for horse, and chariot for chariot: and we will fight against them in the plain, and surely we shall be stronger than they. And he hearkened unto their voice, and did so.
