8:1-6
The Shunammite woman now reappears. Elisha had told her to go away for a famine was coming and would last for seven years, so she went away to the land of the Philistines. After seven years she came back. \in the meantime her land had been taken and she went to the king to hopefully get it back. At the time the king was speaking to Gehazi about Elisha, Gehazi was able to tell the king who the woman was, and her connection to Elisha. There are two key lessons here. One is the faithfulness of the Lord, the other is that the exile was for a period of time only. Kings may have been written for the time that Israel was in exile in Babylon.
8:7-12
The king of Aram became ill and sent someone to Elisha to see if he would recover. This is in contrast to Ahaziah who sent someone to inquire of Baal. So the people of God consult an idol, while the pagan king consults the Lord. see Romans 9-11.1 Elisha tells the king he will recover, but will do harm to Israel. There is a parallel with the response to the gospel. Israel should have accepted Christ, but the Gentiles were more ready to receive Him. Israel should have consulted the Lord, but the pagan nation was more ready to consult the Lord.
