4 Kings 5:13-14

His servants came to him, and said to him: Father, if the prophet had bid thee do some great thing, surely thou shouldst have done it. How much rather what he now hath said to thee: Wash, and thou shalt he clean? Then he went down, and washed in the Jordan seven times: according to the word of the man of God. And his flesh was restored, like the flesh of a little child, and he was made clean.
