1 Kings 20:13, 22

Then a prophet approached Ahab king of Israel and said, “Thus says the LORD: ‘Have you seen all this great army? Behold, I will hand them over to you, and you shall know [without any doubt] that I am the LORD.’ ”

Then the prophet approached the king of Israel and said to him, “Go, strengthen yourself and observe and see what you have to do; for at the first of next year the king of Aram (Syria) will come up against you.”
