John Chrysostom — as excerpted in the Catena Aurea on Matthew 14:1-5

“It is not without reason that the Evangelist here specifies the time, but that you may understand the pride and carelessness of the tyrant; inasmuch as he had not at the first made himself acquainted with the things concerning Christ, but now only after long time. Thus they, who in authority are fenced about with much pomp, learn these things slowly, because they do not much regard them.”
