Daniel 9:24
Seventy weeks have been ordered for your people and your holy city. This time is set to stop their rebellion and put an end to sin. It is set to make atonement for wrongdoing and to bring in righteousness that lasts forever. It is set to seal up vision and prophecy, and to anoint the Most Holy Place.
