Matthew 7:28-8:4

Now when Jesus had finished saying these things, the crowds were astounded at his teaching, for he taught them as one having authority, and not as their scribes.
Jesus Cleanses a Leper
(Mk 1.40—45; Lk 5.12—16)
When Jesus had come down from the mountain, great crowds followed him; and there was a leper who came to him and knelt before him, saying, “Lord, if you choose, you can make me clean.” He stretched out his hand and touched him, saying, “I do choose. Be made clean!” Immediately his leprosy was cleansed. Then Jesus said to him, “See that you say nothing to anyone; but go, show yourself to the priest, and offer the gift that Moses commanded, as a testimony to them.”
