Theophylact of Ohrid

This is not however the paralytic, whose cure is related by John, (John 5) for he had no man with him, this one had four; he is cured in the pool of the sheep market, but this one in a house. It is the same man, however, whose cure is related by Matthew (Matt. 9) and Mark. But mystically, Christ is still in Capernaum, in the house of consolation.
