There are multiple places and references to 3.5 years in Scripture, do they all refer to the same 3.5 years and they all occur concurrently?
I have read the statement that the Bible only has one 3.5 year period, lets lay them out.
Rev 11:2 "But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months."
Then again in verse 3, "And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth."
Rev 13 the beast out of the sea which I believe to be a kingdom, not a man (fwiw), verse 5 "And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months." It should be noted that the forty and two months in this verse say he is given authority over the Saints to overcome them, that is to kill them...I expect this is the Great Trib period of time.
If we back up a chapter to Rev 12:6 we have the woman who gives birth and the child is caught up to God, the woman flees to the wilderness for 1,260 days: "And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days."
Also in chapter 12 we read of the vision of the woman giving birth to the male child, verse 12:14 "And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent."
Then Daniel 7:25 we read "And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time."
Daniel 12:7 "And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.
I expect the two times given in Rev 12 about the woman could be different than the rest, but I wonder if there are more? The two witnesses if in the post AOD 3.5 years would be killed within days of the 1,290 days spoken of in Daniel 12:11. Also the raising of the witnesses there is declared the completion of the second woe (Rev 11:14) The seventh trumpet blows and the outpouring of the bowl judgments begin the third woe, so does the third woe occur in just a matter of days as Daniel 12 mentions that from the AOD to Christ's return or total completion is 1,335 days.
My thinking comes from this. The beast in Rev 13 is given authority over the saints to overcome them (to kill them) for 42 months, wouldn't that include the witnesses? So they witness the first 3.5 years of the 70th week and when the beast is given authority over the Saints on Rev 13:5 he kills the witnesses and begins his reign of terror....finishing the 70th week with 3.5 years of great tribulation...
