Bede the Venerable
Catena Aurea · Lukasevangelium 3
And many other things in his exhortation preached he unto the people. But Herod the tetrarch, being reproved by him for Herodias his brother Philip’s wife, and for all the evils which Herod had done, Added yet this above all, that he shut up John in prison.
But John was not imprisoned in those days. According to St. John’s Gospel it was not till after some miracles had been performed by our Lord, and after His baptism had been noised abroad; but according to Luke he had been seized beforehand by the redoubled malice of Herod, who, when he saw so many flock to the preaching of John, and the soldiers believing, the publicans repenting, and whole multitudes receiving baptism, on the contrary not only despised John, but having put him in prison, slew him.
