(A) "Seventy weeks are determined upon thy people and upon thy holy city,"
-The word determined here actually means "cut off". This 70 weeks are cut off from, or begin at the same time as, the larger 2300 day (year) prophecy of Dan 8:14, which has as it's focus the cleansing of the sanctuary in heaven, the beginning of Judgment. So both the 70 week (490 year) and the 2300 day (year) prophecy begin at the same date.
