2 Kings 5:8

6And he brought the letter to the king of Israel, saying, Now when this letter is come unto thee, behold, I have therewith sent Naaman my servant to thee, that thou mayest recover him of his leprosy.

7And it came to pass, when the king of Israel had read the letter, that he rent his clothes, and said, Am I God, to kill and to make alive, that this man doth send unto me to recover a man of his leprosy? wherefore consider, I pray you, and see how he seeketh a quarrel against me.

8And it was so, when Elisha the man of God had heard that the king of Israel had rent his clothes, that he sent to the king, saying, Wherefore hast thou rent thy clothes? let him come now to me, and he shall know that there is a prophet in Israel.

9So Naaman came with his horses and with his chariot, and stood at the door of the house of Elisha.

10And Elisha sent a messenger unto him, saying, Go and wash in Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean.
