“And Jesus answering said unto him, Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down.”
Mark 13:2 — Greek Interlinear
Church Fathers on Mark 13:2
Because after the founding of the Church of Christ, Judaea was to be punished for her treachery, the Lord fitly, after praising the devotedness of the Church in the person of the poor widow, goes out of the temple, and foretold its coming ruin, and the contempt in which the buildings now so wonderful were soon to be held.
For, since the Lord had spoken much concerning the destruction of Jerusalem, His disciples wondered, that such numerous and beautiful buildings were to be destroyed; and this is the reason why they point out the beauty of the temple, and He answers not only that they were to be destroyed, but also that one stone should not be left upon another.
Here also the Lord enumerates to His disciples the destruction of the last time, that is of the temple, with the people, and its letter; of which one stone shall not be left upon another, that is, no testimony of the Prophets upon those, to whom the Jews perversely applied them, that is, on Ezra, Zerubbabel and the Maccabees.
