Albert Barnes on Mark 2:1

Into Capernaum. Mt 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 Mk 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.
