2 Kings 5:13-14

But Naaman’s servants went to him and talked to him. They said, “Father, if the prophet told you to do some great thing, you would do it, isn’t that right? But he said, ‘Wash, and you will be pure and clean.’” So Naaman did what the man of God said. He went down and dipped himself in the Jordan River seven times, and he became pure and clean. His skin became soft like the skin of a baby.
