2 Kings 5:14-17

14So he went to dip himself in the Jordan River seven times, as the man of God had instructed him. His skin became healthy again like a little child’s skin.

15Then he and all his men returned to the man of God. Naaman stood in front of Elisha and said, “Now I know that there’s no god in the whole world, except the God of Israel. So please accept a present from me.”

16Elisha said, “I solemnly swear, as the Lord whom I serve lives, I will not accept it.” Naaman urged him to take it, but he refused.

17So Naaman said, “If you won’t take it, please have someone give me as much dirt as a pair of mules can carry. From now on I will sacrifice to the Lord alone. I will not offer any burnt offering or sacrifice to any other gods.
