Augustine of Hippo
Catena Aurea · Markusevangelium 6
And the apostles gathered themselves together unto Jesus, and told him all things, both what they had done, and what they had taught. And he said unto them, Come ye yourselves apart into a desert place, and rest a while: for there were many coming and going, and they had no leisure so much as to eat. And they departed into a desert place by ship privately. And the people saw them departing, and many knew him, and ran afoot thither out of all cities, and outwent them, and came together unto him. And Jesus, when he came out, saw much people, and was moved with compassion toward them, because they were as sheep not having a shepherd: and he began to teach them many things.
(de Con. Evan. 2. 45) This is said to have taken place, after the passion of John, therefore what is first related took place last, for it was by these events that Herod was moved to say, This is John the Baptist, whom I beheaded.
