In those days came John the Baptist, preaching in the wilderness of Judaea, John the Baptist - John, surnamed The Baptist, because he required those to be baptized who professed to be contrite because of their sins, was the son of a priest named Zacharias, and his wife Elisabeth, and was born about A. M. 3999, and about six months before our blessed Lord. Of his almost miraculous conception and birth, we have a circumstantial account in the Gospel of Luke, chap. 1: to which, and the notes there, the reader is requested to refer. For his fidelity in reproving Herod for his incest with his brother Philip's wife, he was cast into prison, no doubt at the suggestion of Herodias, the profligate woman in question. He was at last beheaded at her instigation, and his head given as a present to Salome, her daughter, who, by her elegant dancing, had highly gratified Herod, the paramour of her incestuous mother. His ministry was short; for he appears to have been put to death in the 27th or 28th year of the Christian era.
Came - preaching - Κηρυσσων, proclaiming, as a herald, a matter of great and solemn importance to men; the subject not his own, nor of himself, but from that God from whom alone he had received his commission. See on the nature and importance of the herald's office, at the end of this chapter. Κηρυσσειν, says Rosenmuller, de iis dicitur, qui in Plateis, in Campis, in Aere aperto, ut a multis audiantur, vocem tollunt, etc. "The verb κηρυσσειν is applied to those who, in the streets, fields, and open air, lift up their voice, that they may be heard by many, and proclaim what has been committed to them by regal or public authority; as the Kerukes among the Greeks, and the Precones among the Romans."
The wilderness of Judea - That is, the country parts, as distinguished from the city; for in this sense the word wilderness, מדבר midbar or מדבריות midbarioth, is used among the rabbins. John's manner of life gives no countenance to the eremite or hermit's life, so strongly recommended and applauded by the Roman Church.
