2 Kings 5:10-14
New King James Version (NKJV)

10 And Elisha sent a messenger to him, saying, “Go
and wash in the Jordan seven times, and your flesh shall be restored to you, and you
shall be clean.” 11 But Naaman became furious, and
went away and said, “Indeed, I said to myself, ‘He will surely come out to
me, and stand and call on the name of the Lord his God, and wave his hand over the place, and heal the
leprosy.’ 12 Are not the Abanah and the
Pharpar, the rivers of Damascus, better than all the waters of Israel? Could I not wash in them
and be clean?” So he turned and went away in a rage. 13 And his
servants came near and spoke to him, and said, “My father, if the prophet had
told you to do something great, would you not have
done it? How much more then, when he says to you, ‘Wash, and be
clean’?” 14 So he went down and dipped seven times in the
Jordan, according to the saying of the man of God; and his flesh was restored like the flesh of
a little child, and he was clean.
