That a period of peace with the Nation of Israel will take place during the first three and one half years of the Great Tribulation, comes from Chapter 9 of the book of Daniel, and was verified by Jesus in chapter 24 of the book of Matthew.
Daniel 9:24 through 27 KJV
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The week of Daniel chapter 9 is actually a seven year period, and the midst of the week is three and one half years.
Jesus affirmed the prophesy of Daniel in Chapter 24 of the book of Matthew.
Mat 24:14 , 15, 21 and 22 KJV
14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
The famous "70 Weeks" prophecy of Daniel 9 has been called by some Bible scholars
the "backbone" of Bible prophecy because it is the one that "seals up" other
prophecies. If this is true, it would seem to be rather important for those
interested in the interpretation of Bible prophecy to figure it out correctly.
Daniel 9:24 mentions several things that are to be accomplished in the 70 Weeks:
"Seventy weeks are determined upon thy holy city, to finish the transgression, and
to make an end of sins, and to make reconciliation for iniquity, and to bring in
everlasting righteousness, and to seal up the vision and prophecy, and to anoint
the most Holy."
Since this phrase "time, times, and a half" which comes from Daniel's prophecies
is found in Revelation 12:14, it forms an obvious connection or link between the
two books. This period is also given as 1,260 days in Revelation 12:6, 42 months
in chapters 11 and 13. The 1,260 days would be 3.5 years, each year having 12
months of 30 days. In such a scheme, a year would have 360 days, although we know
today the length of the solar year is 365.25 days. Some have postulated there is
such a thing as a "prophetic year" that must be used for calculating the 70 Weeks.
An interesting interpretation of Daniel's 70 Weeks was proposed in 1895 by Sir
Robert Anderson, a brilliant biblical scholar, which made this assumption. Anderson
claimed that from the commandment to rebuild Jerusalem to the appearance of the
Messiah (the seven weeks and threescore and two weeks of verse 25) worked out to
exactly 483 biblical years equalling 360 days, or 173,880 days.
In the solar-lunar calendar used by the Hebrews in ancient times, the length of a
month was determined by the phases of the moon. Our word "month" reflects the
ancient connection with the moon's period. The precise duration of the moon's
period is 29.531 days. It is close to 30 days, but not quite. Because of this,
the ancient calendar which was used by the Babylonians, Hebrews, Greeks, and most
other nations in antiquity had years of varying length. Most years had 12 months
[or 'moons'], but some years had 13 months. The priests of the various nations
would determine the length of the year by observation, and there was a fair bit of
confusion when bad weather interfered with observations of the moon.
The 70 weeks of Daniel are separated into three distinct parts, suggesting that
different units are involved in the various parts. [Or else, why would the 7 weeks,
and the 62 weeks, and one week be mentioned separately?] The emphasis is
on "sevens," and while there may be 7-year periods involved, this may not be true
of all the parts. The three parts to the 70 Weeks prophecy resemble the three
sections or parts in the phrase "time, times, and a half" that are mentioned in
In Daniel 12:7, the phrase "time, times, and a half" is given as the duration of
the period encompassed by his prophecies. The completion of this period, whatever
it means, marks a time when "all these things shall be finished." The pattern which
is evident in the phrase "time, times, and a half" can be applied to two of Daniel's
mysterious time periods, the 1,290 days of Daniel 12:11, and the 1,335 days of Daniel
12:12, to help us understand and explain them. Looking at the pattern imbedded in
the phrase "time, times and a half," we can insert the different units for year
lengths in the three divisions, as a kind of template, to obtain:
Daniel 12:7: time + times + a half
Daniel 12:11: 1290 days = 390 + 2 x 360 + 360/2
Daniel 12:12: 1335 days = 360 + 2 x 390 + 390/2
John in Revelation applies this same pattern to derive his variations on three and
a half years:
Revelation 11:2: 42 months = 12 + 2 x 12 + 12/2
Revelation 11:3: 1260 days = 360 + 2 x 360 + 360/2
Revelation 11:9: 3.5 days = 1 + 2 x 1 + 1/2
Revelation 12:6: 1260 days = 360 + 2 x 360 + 360/2
Revelation 12:14: time + times + a half
Revelation 13:5: 42 months = 12 + 2 x 12 + 12/2
A phrase quite similar to "a time, times and a half" is mentioned in Daniel 7:25;
here it is given as "a time, and times, and the dividing of time." Most Bible
scholars have assumed they are the same, but although the two phrases are similar,
they are not identical. The pattern or structure here is similar to that of the 70
Weeks of Daniel 9:24-27, which has a period of 7 weeks, plus 62 weeks, plus a final
Daniel 7:25: time + times + dividing of time
Daniel 9:24-27: 7 weeks + 62 weeks + divided week = 70 weeks
Now, what about the final, or 70th week? This final week is a figurative period of
seven years, and it is during this "week" that Christ "confirms the covenant with
many," as stated in Daniel 9:27. This period began when Christ began his ministry.
His ministry lasted three and a half years. The prophecy said he would be "cut off,"
a reference to the crucifixion, after 62 weeks [Daniel 9:26].
In the final, 70th week, Christ is to "confirm the covenant with many." This final
week is still in effect, because Christ still "confirms the covenant" with
believers. The first half of this week was the ministry of Christ on the earth. The
last half is symbolic of the entire time of the Church.
