Theophylact of Ohrid
Catena Aurea · Lukasevangelium 9
Now Herod the tetrarch heard of all that was done by him: and he was perplexed, because that it was said of some, that John was risen from the dead; And of some, that Elias had appeared; and of others, that one of the old prophets was risen again. And Herod said, John have I beheaded: but who is this, of whom I hear such things? And he desired to see him.
If John is alive and has risen from the dead, I shall know him when I see him; as it follows, And he sought to see him.
