So, they went to Capernaum [Note: This was a city in Galilee that later became Jesus' headquarters while in Galilee. See verse

And people from all over the city [of Capernaum] gathered at the door of the house,

He said to them, "Let us go on to the next towns so that I can preach there also, for this was why I came out [i.e., Jesus was sent by God to preach to other towns as well as Capernaum. See Luke 4:43]."

After Jesus returned to Capernaum several days later, it became known that He was [back] at home [i.e., possibly at the house of Peter and Andrew, where He was staying. See 1:29].

When Jesus had crossed over again in a boat to the other side [i.e., to the northwest shore of the lake, probably in the vicinity of Capernaum], a large crowd gathered around Him along the shore of the lake.

Then Jesus and His disciples came to Capernaum [Note: This city on the northwest shore of Lake Galilee had become sort of a headquarters for Jesus when He was in this region]. When He [and His disciples] entered a house He asked them, "What were you discussing on the way here?"
