Amongst scholars, it is acceptable interpretation of prophecy to conclude that prophecy will be fulfilled in stages or different periods of time. This is apparent in Daniels 70 weeks prophecy (Daniel 9:24-27) as well as in Isaiah 61:1-3. When he foretells the day of vengeance of our God.
The prophet Daniel spoke as follows:
Seventy weeks are determined for your people and for your holy city, to finish the transgression, to make an end to sins, to make reconciliation for iniquity, to bring in everlasting righteousness, to seal up vision and prophecy,and to anoint the Most Holy. (verse 24)
Know therefore and understand, That from the going forth of the command to restore and build Jerusalem until Messiah the Prince, There shall be seven weeks and sixty-two weeks; The street shall be built again, and the wall, Even in troublesome times. (verse 25)
And after the sixty-two weeks Messiah shall be cut off, but not for Himself; And the people of the prince who is to come Shall destroy the city and the sanctuary. The end of it shall be with a flood, And till the end of the war of desolations are determined. (verse 26)
Then he shall confirm a covenant with many for one week; But in the middle of the week, He shall bring an end to sacrifice and offering. And on the wing of abominations shall be one who makes desolate, even until the consummation, which is determined, is poured out on the desolate. (verse 27)
Notice throughout the four verses Daniel clearly shows the time frames of the Messiah, Seventy weeks; Seven weeks and Sixty-two weeks; and Sixty-Two weeks, respectively. Also notice how in verse 26, Daniel tells how the Messiah will be cut off after Sixty-Two weeks and Jerusalem and the temple will be destroyed. The destruction of the Temple occurred in 70 A.D. Which means the Messiah had to come prior to that date and be cut off, Messiah's first coming. Next, note in verse 24 that Seventy weeks are needed "to bring everlasting righteousness... and to anoint the Most Holy" the Messiah's second coming.
Isaiah's prophecy is similar in regards to the separation of time; however, it is not readily apparent to the reader.
The Spirit of the Lord God is upon me: because the Lord has anointed me to preach good tidings unto the meek; he has sent me to bind up the broken hearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound (verse 1); to proclaim the year of the Lord God's favor. And the day of vengeance of our God; To comfort all who mourn (verse 2); To console those who mourn in Zion, To give them beauty for ashes, The oil for joy for mourning, The garment of praise for the spirit of heaviness; That they may be called trees of righteousness, The planting of the Lord, that He may be glorified (verse 3).
Notice after verse one Isaiah states that the Messiah will "proclaim the year of the Lord God's favor". This is reflective of the Messiah's first coming. Next, Isaiah continues with the prophecy by stating in the remaining parts of verse two and three, "the day of vengeance of Our God; to comfort all who mourn...The planting of the Lord, that He may be glorified", is reflective of the Messiah's second coming.
In the book of Luke chapter 4 verses 16-21, Yeshua (Jesus) clarifies this separation when He stated, "To proclaim the acceptable year of the Lord", and then sat down and said, " Today, this scripture is fulfilled in your hearing." This was Messiah's first coming. Thus, leaving "the day of vengeance of Our God" remaining for His [Yeshua's] second coming.
