1 Kings 22:3-5

3The king of Israel said to his leaders, ‘You know that Ramoth Gilead belongs to us. But we are not doing anything to take it back from the king of Syria.’

4So the king of Israel asked Jehoshaphat, ‘Will you go with me to attack Ramoth Gilead?’ Jehoshaphat said to the king of Israel, ‘Yes, we should work together! Use my soldiers and my horses as if they belonged to you.’

5Then Jehoshaphat said to the king of Israel, ‘Before we go to fight, we must ask the Lord what we should do.’
