Albert Barnes 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)

Into Capernaum. See Barnes' Notes on Matthew 4:13.

After some days. The number of days is not known. Probably he remained long enough in the desert to heal the sick that were brought to him, and to give instructions to the multitudes that attended his preaching. Capernaum was not the city mentioned in Mark 1:45, and it is probable that there was no difficulty in his remaining there and preaching.

And it was noised, etc. He entered the city, doubtless, privately; but his being there was soon known; and so great had his popularity become, that multitudes pressed to hear him.
