"Sir Isaac Newton provided the key to understanding the seventy weeks prophecy of Daniel. When one reckons from the day that Ezra left to rebuild Jerusalem (Sat 3 Apr 458 BC), to one of the two possible dates for the Crucifixion (Fri 1 Apr AD 33), the interval is almost exactly seventy weeks of years (490 years) on our calendar. When the Enoch calendar is used, then the separation of the two dates completes exactly seventy weeks of Enoch years, to the very day. This precise timing provides a strong witness 1) of God's foreknowledge of both dates, 2) of the authenticity of the Book of Daniel, and 3) of Fri 1 Apr AD 33 as the date of the Crucifixion of Jesus Christ. Truly the Lord has provided several witnesses of the key dates in the Savior's life."
