《汉书·传·王莽传中》
皇帝谦虚地推辞，用摄皇帝的名义代居皇位，还不能够符合上天的心意，因此那年秋季七月，上天又加上三台星和文马。
皇帝谦让，以摄居之，未当天意，故其秋七月，天重以三能文马。
The emperor humbly declined and took the place of the throne as Acting Emperor, he still could not satisfy Heaven’s intention, so that autumn in July of that year, Heaven added the Three Stars and the Literary Horse.
