John Calvin on Matthew 14:1

The reason why the Evangelists relate this occurrence is, to inform us that the name of Christ was universally celebrated, and, therefore, the Jews could not be excused on the plea of ignorance. Many might otherwise have been perplexed by this question, “How came it that, while Christ dwelt on the earth, Judea remained in a profound sleep, as if he had withdrawn into some corner, and had displayed to none his divine power?” The Evangelists accordingly state, that the report concerning him was everywhere spread abroad, and penetrated even into the court of Herod.
