"We will starve if we stay here, and we will starve if we go back into the city. So we might as well go out and surrender to the Aramean army. If they let us live, so much the better. But if they kill us, we would have died anyway."
So that evening they went out to the camp of the Arameans, but no one was there!
For the Lord had caused the whole army of Aram to hear the clatter of speeding chariots and the galloping of horses and the sounds of a great army approaching. "The king of Israel has hired the Hittites and Egyptians to attack us!" they cried out.

So they panicked and fled into the night, abandoning their tents, horses, donkeys, and everything else, and they fled for their lives.
When the lepers arrived at the edge of the camp, they went into one tent after another, eating, drinking wine, and carrying out silver and gold and clothing and hiding it.
Finally, they said to each other, "This is not right. This is wonderful news, and we aren't sharing it with anyone! If we wait until morning, some terrible calamity will certainly fall upon us. Come on, let's go back and tell the people at the palace."
So they went back to the city and told the gatekeepers what had happened -- that they had gone out to the Aramean camp and no one was there! The horses and donkeys were tethered and the tents were all in order, but there was not a single person around.
Then the gatekeepers shouted the news to the people in the palace.
