The same day— This is the plain and literal meaning of the original, and it may be understood of the day when the mother and relations of our Saviour came to him. It must however be observed, that this expression is not always to be taken literally, but may only signify at that time, or on a certain day,—on one of those days, as St. Luke words it, Luke 5:17. It seems the calumnies of the Pharisees had not the effect intended; for the crowd was now become so great, that neither the house, nor the court before it, could contain the people who came; Jesus therefore carried them out to the sea-side, and taught them: and because there were many still coming and going, he judged it necessary to enter into a boat, for the conveniency of being heard and seen by all, which he might easily be, if the shore thereabouts was somewhat circular and declining, after the manner of an amphitheatre. Thus commodiously seated in the vessel, he delivered many doctrines of the highest importance, making choice of such for the subject of his sermons, when he had the greatest number of hearers, because there was a probability of doing the most good by them.
