Naaman stood at the door of the house of Elisha Waiting for Elisha's coming to him. And Elisha sent a messenger, &c. Which he did partly to try and exercise Naaman's faith and obedience; partly for the honour of his religion and ministry, that it might appear he sought not his own glory and profit, but only God's honour and the good of men; and partly for the manifestation of the almighty power of God, which could cure such a desperate disease by such slight means.
