I Kings 20:13, 28

Suddenly a prophet approached Ahab king of Israel, saying, “Thus says the LORD: ‘Have you seen all this great multitude? Behold, I will deliver it into your hand today, and you shall know that I am the LORD.’ ”

Then a man of God came and spoke to the king of Israel, and said, “Thus says the LORD: ‘Because the Syrians have said, “The LORD is God of the hills, but He is not God of the valleys,” therefore I will deliver all this great multitude into your hand, and you shall know that I am the LORD.’ ”
