2 Kings 7:12 (KJV)

So they came and called unto the porter of the city: and they told them, saying, We came to the camp of the Syrians, and, behold, there was no man there, neither voice of man, but horses tied, and asses tied, and the tents as they were.

And he called the porters; and they told it to the king’s house within.

And the king arose in the night, and said unto his servants, I will now shew you what the Syrians have done to us. They know that we be hungry; therefore are they gone out of the camp to hide themselves in the field, saying, When they come out of the city, we shall catch them alive, and get into the city.

And one of his servants answered and said, Let some take, I pray thee, five of the horses that remain, which are left in the city, (behold, they are as all the multitude of Israel that are left in it: behold, I say, they are even as all the multitude of the Israelites that are consumed:) and let us send and see.

They took therefore two chariot horses; and the king sent after the host of the Syrians, saying, Go and see.
