Luke 5:12-14

And it came to pass, while he was in one of the cities, behold, a man full of leprosy: and when he saw Jesus, he fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean. And he stretched forth his hand, and touched him, saying, I will; be thou made clean. And straightway the leprosy departed from him. And he charged him to tell no man: but go thy way, and show thyself to the priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them.
