Origen
Catena Aurea · Matthäusevangelium 24
Watch therefore: for ye know not what hour your Lord doth come. But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up. Therefore be ye also ready: for in such an hour as ye think not the Son of Man cometh.
Those of more plain understanding say, that He spoke this of His second coming; but others would say that it applies to an intellectual coming of the word into the understanding of the disciples, for as yet He was not in their understanding as He was to be.
