‘And the vision of the evenings and mornings which has been told is true. But shut up the vision for it belongs to many days.'
Compare Daniel 8:14. The spoken vision of the evenings and the mornings was of the period when the temple was desecrated, whether by a the ministrations of a false High Priest (Menelaus) or by the altar of Zeus. It would be a heavy burden for Israel if they considered the fact, that the sanctuary that they would so painfully erect would again be desecrated, and almost unbelievable that God would allow it. But Daniel is assured that it will indeed be so, but that it will not be for a long time. So the vision was not to be read out as though it could happen at any time. It was to be kept on one side and preserved with a recognition that it spoke of a distant future and in those days would prove a comfort and a strength.
