Charles Ellicott Commentary Mark 2:1

"And when he entered again into Capernaum after some days, it was noised that he was in the house." — Mark 2:1 (ASV)

And again he entered into Capernaum.—See Notes on Matthew 9:1-8. St. Mark alone names Capernaum, St. Matthew describing it as “His own city.” The house may have been Peter’s, as before in Mark 1:29.
