First reading: 2 Kings 5:14-17

Naaman the leper went down and immersed himself seven times in the Jordan, as Elisha had told him to do. And his flesh became clean once more like the flesh of a little child.
  
Returning to Elisha with his whole escort, he went in and stood before him. ‘Now I know’ he said ‘that there is no God in all the earth except in Israel. Now, please, accept a present from your servant.’
  
But Elisha replied, ‘As the Lord lives, whom I serve, I will accept nothing.’ Naaman pressed him to accept, but he refused.
  
Then Naaman said, ‘Since your answer is “No,” allow your servant to be given as much earth as two mules may carry, because your servant will no longer offer holocaust or sacrifice to any god except the Lord.’
