1. The Arameans fled (3-15)

Four lepers deduced that the best bet for survival was to surrender to the Aramean army besieging the city. When they arrived at the enemy camp, they saw that the enemy had deserted their camp in haste leaving all their belongings -- and food -- behind! Verse 6 says, "...for the Lord had caused the Arameans to hear the sound of chariots and horses and a great army..." and they fled for their lives. After carrying away some booty, the lepers realized they couldn't keep this good news to themselves and reported it in the city. The king assumed it was a ruse and sent a scouting party to check it out. They followed the Arameans up to the Jordan and knew they were long gone.

2. The promise of deliverance fulfilled (15-20)

That day, as Elisha prophesied, food flowed in the city and was sold at an economical price. The king's assistant who doubted God's deliverance was trampled at the gate as people rushed out to loot the Aramean camp.
