Naaman

One of the most striking of Elisha's miracles involved Naaman. From the Bible Dictionary:

Naaman

Syrian noble cured of leprosy by Elisha (2 Kgs. 6; Luke 4: 27). He came to Elisha at the suggestion of a little Hebrew maid, captured in war (2 Kgs. 5: 2-3). He was ordered to bathe seven times in the Jordan, which, after some hesitation, he did, and was cured. He showed his gratitude by returning to Samaria, a distance of 30 miles, to thank Elisha. The prophet refused to accept any payment, and his servant Gehazi was punished for taking Naaman’s present. Naaman took with him to Syria two mules’ burden of earth (2 Kgs. 5: 17), on which he intended to erect an altar to Jehovah. He did this because he believed that the God of Israel could only be worshipped on Israelitish soil.
