Augustine of Hippo
Catena Aurea · Matthäusevangelium 14
At that time Herod the tetrarch heard of the fame of Jesus. And said unto his servants, This is John the Baptist; he is risen from the dead; and therefore mighty works do shew forth themselves in him. For Herod had laid hold on John, and bound him, and put him in prison for Herodias’ sake, his brother Philip’s wife. For John said unto him, It is not lawful for thee to have her. And when he would have put him to death, he feared the multitude, because they counted him as a prophet.
(ubi sup.) Luke’s words are, John have I beheaded: who is he of whom I hear such things? (Luke 9:9.) As Luke has thus represented Herod as in doubt, we must understand rather that he was afterwards convinced of that which was commonly said—or we must take what he here says to his servants as expressing a doubt—for they admit of either of these acceptations.
