Daniel 9:20-27
The Seventy "Sevens"

    20 While I was speaking and praying, confessing my sin and the sin of my people Israel and making my request to the LORD my God for his holy hill- 21 while I was still in prayer, Gabriel, the man I had seen in the earlier vision, came to me in swift flight about the time of the evening sacrifice. 22 He instructed me and said to me, "Daniel, I have now come to give you insight and understanding. 23 As soon as you began to pray, an answer was given, which I have come to tell you, for you are highly esteemed. Therefore, consider the message and understand the vision:

    24 "Seventy 'sevens' [c] are decreed for your people and your holy city to finish [d] transgression, to put an end to sin, to atone for wickedness, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the most holy. [e]

    25 "Know and understand this: From the issuing of the decree [f] to restore and rebuild Jerusalem until the Anointed One, [g] the ruler, comes, there will be seven 'sevens,' and sixty-two 'sevens.' It will be rebuilt with streets and a trench, but in times of trouble. 26 After the sixty-two 'sevens,' the Anointed One will be cut off and will have nothing. [h] The people of the ruler who will come will destroy the city and the sanctuary. The end will come like a flood: War will continue until the end, and desolations have been decreed. 27 He will confirm a covenant with many for one 'seven.' [i] In the middle of the 'seven' [j] he will put an end to sacrifice and offering. And on a wing of the temple he will set up an abomination that causes desolation, until the end that is decreed is poured out on him. [k] " [l]

The following is from Pastor Mark Carey of Fellowship Bible Church in Winchester, Virginia:

70 Sevens represents 490 (years).

 

Nehemiah 2 was around March 5, 444 BC.

 

7 sevens + 62 sevens = 69 sevens = 69 units of 7 = 483 years. 

483 X 360 (Babylonian) = 173880 = March 30, 33AD (Triumphal Entry).

444BC to AD 33 =  476 Solar Years = 476 X 365.242 = 173855.

Another 25 days would cover the Passover of AD 33 (March 5-30 of AD 33) = 173880, the same number of days given the 69 units of 7 (483 years).
