1 Kings 20:22-24

22After the battle, the prophet came to the king of Israel again. He said to him, ‘Now go and make your army strong. Decide what you need to do. Do this, because next spring the king of Syria will attack you again.’

23At the same time, some of the king of Syria's officers said to him, ‘The gods of the Israelites are gods who live in the hills. That is why the Israelites were too strong for us. But if we fight them on the lower ground, we will surely be stronger than them.

24You should do this: Remove all the other kings. Put your own officers to lead the army instead.
