Matthew 8: 1 - 4
1 When he came down from the mountain, great crowds followed him;
2 and behold, a leper came to him and knelt before him, saying, "Lord, if you will, you can make me clean."
3 And he stretched out his hand and touched him, saying, "I will; be clean." And immediately his leprosy was cleansed.
4 And Jesus said to him, "See that you say nothing to any one; but go, show yourself to the priest, and offer the gift that Moses commanded, for a proof to the people."
