Luke 5:12

One of the cities of Galilee is what Luke meant in view of the context. He revealed his particular interest in medical matters again by noting that leprosy covered this man completely. There could be no doubt that he was a leper. As Peter had done, this man fell on His face before Jesus (cf. Luke 5:8). As Peter, he also appealed to Jesus as "Lord" (Luke 5:8). This address was respectful and appropriate for addressing someone with special power from God. [Note: G. Vermes, Jesus the Jew, pp. 122-23.] The leper was very bold in coming to Jesus since his leprosy separated him from normal social contacts. His conditional request cast doubt on Jesus’ willingness to heal him, not His ability to do so. It may express his sense of unworthiness to receive such a blessing.
