worshipped. did homage. See App-137. The variations in Mark 1, and Luke 5, are due to the fact that they do not record the same miracle. See App-97.
Lord. App-98. This is the first time that Jesus is called "Lord". In this second period of His ministry, His Person is to be proclaimed as Messiah, both Divine (here), and in Matthew 8:20 human. When once they begin to call Him "Lord", they continue. Compare verses: Matthew 8:8; Matthew 8:6, &c.
clean. See note on Matthew 8:3. Not the same miracle as in Mark 1:40 and Luke 5:12. Here both without the city (Capernaum, App-169); there, both within (probably Chorazin), for the leper was "full" and therefore "clean" (Leviticus 13:12; Leviticus 13:13). Here, the leper obeys and is silent; there, he disobeys, so that the Lord could no more enter the city (Chorazin). The antecedents were different, and the consequents also, as may be seen from the two records.
