Mark 1:43

39 He went into their synagogues throughout all Galilee, preaching and casting out demons.

40 There came to him a leper, begging him, kneeling down to him, and saying to him, "If you want to, you can make me clean."

41 Being moved with compassion, he stretched forth his hand, and touched him, and said to him, "I want to. Be made clean."

42 When he had said this, immediately the leprosy departed from him, and he was made clean.

43 He strictly charged him, and immediately sent him out,

44 and said to him, "See you say nothing to anybody, but go show yourself to the priest, and offer for your cleansing the things which Moses commanded, for a testimony to them."

45 But he went out, and began to proclaim it much, and to spread about the matter, so that Jesus could no more openly enter into a city, but was outside in desert places: and they came to him from everywhere.
