Pseudo-Chrysostom
Catena Aurea · Markusevangelium 6
And king Herod heard of him; (for his name was spread abroad:) and he said, That John the Baptist was risen from the dead, and therefore mighty works do shew forth themselves in him. Others said, That it is Elias. And others said, That it is a prophet, or as one of the prophets. But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead.
(Vict. Ant. e Cat. in Marc.) It seems to me that this prophet means that one of whom Moses said, God will raise up a prophet unto thee of thy brethren. (Deut. 8:15.) They were right indeed, but because they feared to say openly, This is the Christ, they used the voice of Moses, veiling their own surmise through fear of their rulers. There follows, But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead. Herod expressly says, this in irony.
