Second Kings 6:24—7:20 tells us that Ben-hadad king of Syria besieged Samaria.
There was a great famine in Samaria (6:25-29). The famine was severe to such an extent that the people would eat their children.
Jehoram king of Israel was angry with Elisha and tried to kill him (vv. 30-33).
In 7:1-20 Elisha prophesied that on the next day there would be a rich provision of food by God's defeating of the Syrians.
The captain who upheld the king did not believe that there could be such a rich provision of food, saying, "Even if Jehovah made windows in heaven, could this thing happen?" (v. 2a). Elisha told him that his eyes would indeed see it but that he would not eat from it.
Four lepers discovered the rich provision of food and reported the good news to the king's household. The king's servants checked out the situation and confirmed the report of the lepers (vv. 3-15).
The people of Israel went forth to plunder the camp of the Syrians. They trampled the unbelieving captain in the gate, and he died as Elisha had said (vv. 16-20).
