Chapter 4 records a number of incidents where God did miraculous deeds through Elisha on behalf of others. He provided for a widow and her sons through providing unlimited oil to fill all the pots she could find. He gave an old woman a son and when he died he raised the boy from the dead again. He also cured poisonous food and fed 100 men with only twenty loaves of barley bread. Some of these miracles are similar to what Jesus would do. Instead of feeding 100 men he fed 4000 and 5000. Elisha is thus established as one of the great prophets.
In chapter 5 it is established among the nations that Elisha is a prophet of the True God. Naaman, a foreign military leader, sought cleansing for a skin disease and found it when he obeyed Elisha’s command to bathe seven times in the Jordan. This took an act of faith and resulted in his belief: “Now I know that there is no God in all the world except in Israel” (5:15) and furthermore, “your servant will never again make burnt offerings and sacrifices to any other god but the LORD” (v17).
Although Elisha worked on the Lord’s behalf not everything was easy for him. Although he could easily see God’s support and prevented Israel from being defeated by Aram he was not respected by the king when things looked bleak. The thinking was that if he and God could help them then if evil befell the nation blame could be placed on his shoulders.
