2 Kings 6:10-14

And the king of Israel sent scouts to the place about which the man of God had told him; so he warned him, so that he was on his guard there, more than once or twice.

Now the heart of the king of Aram was enraged over this matter; and he called his servants and said to them, “Will you not tell me which of us is for the king of Israel?”

One of his servants said, “No, my lord, the king; but Elisha, the prophet who is in Israel, tells the king of Israel the words that you speak in your bedroom.”

So he said, “Go and see where he is, so that I may send men and take him.” And it was told to him, saying, “Behold, he is in Dothan.”

So he sent horses and chariots and a substantial army there, and they came by night and surrounded the city.
