Wednesday Bible Study: What's wrong with this story?

As you may recall from last time, the Syrians are besieging Samaria (the northern kingdom) and the people are eating their children. Yeah, bummer. So Elisha predicts that by the next morning, the famine will be over and food will be cheap. A high ranking officer scoffs at this so Elisha tells him, it will happen but he won't get to eat any of it.

We then return to the new-found focus on lepers, four of whom discover that God has sent the Syrians an auditory hallucination of an attack, causing them to flee. Strangely, however, they don't ride away on their horses, they leave their horses tied up and apparently flee on foot. So the lepers eat their fill, steal some shit, then decide they had better tell the king what has happened. After some doubt, the people plunder the Syrian camp and food is now cheap. As his reward for doubting Elisha, the captain is trampled to death. 

This, obviously, holds an important moral and theological lesson, if you can tell me what it is.

7 ¹ But Eli′sha said, “Hear the word of the Lord: thus says the Lord, Tomorrow about this time a measure of fine meal shall be sold for a shekel, and two measures of barley for a shekel, at the gate of Samar′ia.” ² Then the captain on whose hand the king leaned said to the man of God, “If the Lord himself should make windows in heaven, could this thing be?” But he said, “You shall see it with your own eyes, but you shall not eat of it.”

The Arameans Flee

³ Now there were four men who were lepers at the entrance to the gate; and they said to one another, “Why do we sit here till we die? ⁴ If we say, ‘Let us enter the city,’ the famine is in the city, and we shall die there; and if we sit here, we die also. So now come, let us go over to the camp of the Syrians; if they spare our lives we shall live, and if they kill us we shall but die.” ⁵ So they arose at twilight to go to the camp of the Syrians; but when they came to the edge of the camp of the Syrians, behold, there was no one there. ⁶ For the Lord had made the army of the Syrians hear the sound of chariots, and of horses, the sound of a great army, so that they said to one another, “Behold, the king of Israel has hired against us the kings of the Hittites and the kings of Egypt to come upon us.” ⁷ So they fled away in the twilight and forsook their tents, their horses, and their asses, leaving the camp as it was, and fled for their lives. ⁸ And when these lepers came to the edge of the camp, they went into a tent, and ate and drank, and they carried off silver and gold and clothing, and went and hid them; then they came back, and entered another tent, and carried off things from it, and went and hid them.

⁹ Then they said to one another, “We are not doing right. This day is a day of good news; if we are silent and wait until the morning light, punishment will overtake us; now therefore come, let us go and tell the king’s household.” ¹⁰ So they came and called to the gatekeepers of the city, and told them, “We came to the camp of the Syrians, and behold, there was no one to be seen or heard there, nothing but the horses tied, and the asses tied, and the tents as they were.” ¹¹ Then the gatekeepers called out, and it was told within the king’s household. ¹² And the king rose in the night, and said to his servants, “I will tell you what the Syrians have prepared against us. They know that we are hungry; therefore they have gone out of the camp to hide themselves in the open country, thinking, ‘When they come out of the city, we shall take them alive and get into the city.’” ¹³ And one of his servants said, “Let some men take five of the remaining horses, seeing that those who are left here will fare like the whole multitude of Israel that have already perished; let us send and see.” ¹⁴ So they took two mounted men, and the king sent them after the army of the Syrians, saying, “Go and see.” ¹⁵ So they went after them as far as the Jordan; and lo, all the way was littered with garments and equipment which the Syrians had thrown away in their haste. And the messengers returned, and told the king.

¹⁶ Then the people went out, and plundered the camp of the Syrians. So a measure of fine meal was sold for a shekel, and two measures of barley for a shekel, according to the word of the Lord. ¹⁷ Now the king had appointed the captain on whose hand he leaned to have charge of the gate; and the people trod upon him in the gate, so that he died, as the man of God had said when the king came down to him. ¹⁸ For when the man of God had said to the king, “Two measures of barley shall be sold for a shekel, and a measure of fine meal for a shekel, about this time tomorrow in the gate of Samar′ia,” ¹⁹ the captain had answered the man of God, “If the Lord himself should make windows in heaven, could such a thing be?” And he had said, “You shall see it with your own eyes, but you shall not eat of it.” ²⁰ And so it happened to him, for the people trod upon him in the gate and he died.
