Theophylact of Ohrid
Catena Aurea · Markusevangelium 11
And Jesus entered into Jerusalem, and into the temple: and when he had looked round about upon all things, and now the eventide was come, he went out unto Bethany with the twelve. And on the morrow, when they were come from Bethany, he was hungry: And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon: and when he came to it, he found nothing but leaves; for the time of figs was not yet. And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever. And his disciples heard it.
Wishing to shew His disciples that if He chose He could in a moment exterminate those who were about to crucify Him. In a mystical sense, however, the Lord entered into the temple, but came out of it again, to shew that He left it desolate, and open to the spoiler.
