Using the dating determined by Bishop Ussher, the first attempt to equate these Biblical time periods with the outline given by Enoch in his Apocalypse of Weeks resulted in a shortfall of 52years.

Being convinced that the outline plan of Enoch's timescale is correct, it has been necessary to examine each time element in order to discover if Enoch's times were correct.  Two of the elements are known for their uncertainty:

1.   Previous studies based upon the supposition that the sin of Adam occurred around the year 4000bc, have concluded that the ministry of The Lord Jesus Christ commenced at the time of the 29th Jubilee. There is little doubt that His announcement in the synagogue, quoting the statement of Isaiah was made in a Jubilee year because of His presence in Nazareth at that time in 27ad......'the acceptable year of the Lord' [Luke 4:19]. However there is uncertainty regarding the actual number of of the Jubilee, 29.  From a numerological point of view the better number would be 30 [10 x 3], having the authority of ordinal perfection and The Godhead.     

Daniel's prophesy relating 70 weeks of years [10 Jubilees] to the city and people of Israel commenced at the time when The Christ began His ministry in 27ad.  The Second Coming, or parousia would therefore occur on the 39th Jubilee. This figure also seems to be inappropriate, the 40th [5 x 8] Jubilee being more acceptable for such an important event, therefore the dating base figure of the 30th Jubilee at the beginning of The Christ's ministry in 27ad, has been accepted. 

Applying this conclusion is confirmed by the fact that in Gabriel's statement to Daniel, the first seven weeks are separated from the following sixtytwo........'seven weeks, three score and two weeks',  Why did Gabriel simply not say....three score and nine weeks ?  We now know that the first seven weeks are separated from the sixtytwo for the purpose of the introduction of The Kingdom of God in Israel by the ministry of The Christ working with His apostles. Part of the separated 7 weeks of years have passed between 27ad and 62ad [35 years], when the Jews were Spiritually blinded. 14years remain.

After the completion of the first 35 years, God imposed the loss of Spiritual understanding upon the Jews. This imposition lasts 1960 years [40 Jubilees]. The nations have benefited  during this period by being the source of God's Salvation and experiencing His Administration of Grace. It also lasts for 1960 years. See item 3 below.

Therefore in 2022ad the Jews will regain their Spiritual understanding and in the remaining 14 years of the first 49years all Israel will be gathered by 2036ad, at the 80th Jubilee, when the resurrected King David will be re-established upon the throne of Israel. The details of this are shown on the charts below.

2.   There is considerable uncertainty concerning the number of years from the time that the Israelites crossed the  Jordan into The Land, to the occasion when they were able to make the first planting of their seed at the opening year  of the first Jubilee. When considering the length of time for the battles to clear the land of its existing occupants, seven years seemed to be appropriate. Scripture does not state a figure for this period, although it does for every other item in the list. For this reason, I believe that the time taken for these battles followed by the allotting and occupying of the land between the 12 tribes could easily have taken 10 years.

3.  The third element was not known to Enoch and therefore was not included in his Apocalypse of Weeks. This is the length of time occupied by the present Administration of God's Grace. This is known to be 1960 years [49 x 40], ending at the phanerOsis of Christ in 2029ad.

One of the passages which reveals this Administration is given in Ephesians chapter 3 verses 2, 3, 8, and 9. There are two mysteries referred to. The parenthetical part of this passage includes verses 4 to 7, concerning the acknowledgement of the Deity of The Christ, [even as the Apostle Thomas did] and is known as The Messianic Mystery. It was not published abroad during The Christ's first parousia.  

The mystery at the beginning and end of this passage [verses 2, 3, 8, 9.] relates to an Administration [gk: oikonomia],  The Administration of The Grace of God. It  was revealed to Paul shortly before he wrote the following words in his letter to the 'Ephesians'. Prior to that, as it says, it was 'hidden away from the eons in God'. 

4.  Enoch was also unaware of the fourth element, The Administration of The Fullness of Times., which God introduces before The Day of God. It is the last item in the list below and was revealed also by the apostle Paul [Ephesians 1:10]. The number of years required for this Administration, together with the 1960 years of the third item above, plus the years of the last four weeks of Enoch's Apocalypse [4 x 700] must total 4900 years being one third of the number of years between 'In the beginning God created the Heaven and the Earth' and The Day of God. See The Grand Plan of God. Thus this fourth element has a time span of 140years [2800 + 1960 + 140]

The chart below shows firstly the condition conforming to Enoch's Apocalypse of Weeks and secondly the extended Apocalypse with the two additional Administrations revealed only to the apostle Paul in 65ad.
