2 Kings 6:9-11

New King James Version

⁹ And the man of God sent to the king of Israel, saying, “Beware that you do not pass this place, for the Syrians are coming down there.” ¹⁰ Then the king of Israel sent someone to the place of which the man of God had told him. Thus he warned him, and he was watchful there, not just once or twice.

¹¹ Therefore the heart of the king of Syria was greatly troubled by this thing; and he called his servants and said to them, “Will you not show me which of us is for the king of Israel?”
