2 Kings 5

2 Kings 5:14-16 (KJV)
14 Then went he down, and dipped himself seven times in Jordan, according to the saying of the man of God: and his flesh came again like unto the flesh of a little child, and he was clean.
15 And he returned to the man of God, he and all his company, and came, and stood before him: and he said, Behold, now I know that there is no God in all the earth, but in Israel: now therefore, I pray thee, take a blessing of thy servant.
16 But he said, As the Lord liveth, before whom I stand, I will receive none. And he urged him to take it; but he refused.

2 Kings 5:9-12 (KJV)
9 So Naaman came with his horses and with his chariot, and stood at the door of the house of Elisha.
10 And 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.
11 But Naaman was wroth, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of the Lord his God, and strike his hand over the place, and recover the leper.
12 Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage.
