Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 9:30-37

“It is after miracles that the Lord inserts a discourse concerning His Passion, lest it should be thought that He suffered because He could not help it; wherefore it is said, And they departed thence, and passed through Galilee: and he would not that any man should know it. For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him.”
