All the city - A great part of the city. A great multitude from the city.
And all the city was gathered together at the door. That is, the inhabitants of the city of Capernaum, a very great number of them at least, who having either heard of, or seen the dispossession of the unclean spirit in the synagogue in the daytime; and being willing to see what miraculous cures might be wrought by Christ upon the diseased and possessed that were brought to him, got together in great crowds about the door of the house of Simon and Andrew where Jesus now was.
And all the city was gathered together at the door--of Peter's house; that is, the sick and those who brought them, and the wondering spectators. This bespeaks the presence of an eye-witness, and is one of those lively examples of word-painting so frequent in this Gospel.
And the whole city was gathered together at the door - O what a fair prospect was here! Who could then have imagined that all these blossoms would die away without fruit?
