According to Daniel verses 9:3 through 9:19 Daniel prayed for answers ...Prophecies of Messiah Jesus according to Moses, Isaiah, and others; men of God identified who He is, His purpose, and what He would do; and\ or fulfill. Moses described what should be considered (or looked for) in order to identify Him (review Deuteronomy 18:15 through 18:22). And Daniel in his Chapter 9, "prophecy of Seventy (70) weeks", revealed the precise time of Messiah, Jesus' first (1st) arrival, and appearing in His Ministry; for all to witness: Daniel 9:24 ...Seventy (70) weeks (or weeks of years, which are; 490 years = 70 x 7) are determined upon thy people and upon thy holy city (Jerusalem) ...Daniel 9:27 ...And he (Messiah/ Jesus ; the subject of the previous verses is about Messiah, not man of sin) shall confirm the covenant with many for one week (or 7 years): and in the midst of the week or after one half week of ministry] he
(Jesus) shall cause the (animal) sacrifice and the oblation to cease.
