Mark 1:40

And there came a leper to him,.... After he was come down from a certain mountain, in Galilee, where he had been preaching to the people, Matthew 8:1, and when be was in a certain city, Luke 5:12, either Capernaum, or some other city of Galilee. This man was full of leprosy, as Luke says, and very probably deemed incurable; of the nature and symptoms of the leprosy, Luke 5:12,

beseeching him; to cure him of his leprosy:

and kneeling down to him; in token of submission, respect, and reverence, and to worship him:

and saying unto him, if thou wilt thou canst make me clean;

Matthew 8:2. Mark omits the word "Lord".
