Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 11:1-10

“Now consider how many things the Lord foretold to His disciples, that they should find a colt; wherefore it goes on, And as soon as ye be entered into it, ye shall find a colt tied, whereon never man sat, loose him, and bring him; and that they should be impeded in taking it, wherefore there follows, And if any man say unto you, Why do ye this? say ye, The Lord hath need of him; and that on saying this, they should be allowed to take him; wherefore there follows, And straightway he will send him hither; and as the Lord had said, so it was fulfilled. Thus it goes on: And they went their way, and found the colt tied by the door without, in a place where two ways meet; and they loose him.”
