2 Kings 5:13-14

131Then his servants approached and spoke to him, 2saying, “3My father, had the prophet told you to do some great thing, would you not have done it? How much more then, when he says to you, ‘Wash, and be clean’?” 14So he went down and dipped himself in the Jordan seven times, in accordance with the word of the man of God; and 4his flesh was restored like the flesh of a little child, and 5he was clean.
