Rabanus Maurus — as excerpted in the Catena Aurea on Matthew 13:1-9

“For not only the Lord’s words and actions, but His journeyings also, and the places in which He works His mighty works and preaches, are full of heavenly sacraments. After the discourse held in the house, wherein with wicked blasphemy He had been said to have a dæmon, He went out and taught by the sea, to signify that having left Judæa because of their sinful unbelief, He would pass to the salvation of the Gentiles. For the hearts of the Gentiles, long proud and unbelieving, are rightly likened to the swelling and bitter waves of the sea. And who knows not that Judæa was by faith the house of the Lord.”
