2 Kings 6:8-10

Elisha Traps Blinded Arameans 8Now the king of Aram was at war with Israel. After conferring with his officers, he said, “I will set up my camp in such and such a place.” 9The man of God sent word to the king of Israel: “Beware of passing that place, because the Arameans are going down there.”

10So the king of Israel checked on the place indicated by the man of God. Time and again Elisha warned the king, so that he was on his guard in such places.
