Since we know the foundational timing structure of the tribulation period, we can use it as a timeline to place the other events spoken of in Revelation in their proper timing sequence.
I will only be interjecting in 2 areas which I fully understand; The timing of the 3 woe's, and the final 45 days being shortened to a lesser amount of days, as told to us by Yeshua in Matthew 24, Mark 13 and Luke 21.
The timing is explicitly written in the 12th chapter of Daniel. The scribe of Matthew and the scribe of Mark, both had found it necessary to alert the reader: "He who reads this, let him understand."
They are pointing to the book of Daniel, chapter 12 where the Melek (angel) is speaking to Daniel about these future events but Daniel is not understanding. The melek then tells him of the 2 key events to watch for and their exact timing which relate directly to the timing of the return of Yeshua. That is; The daily sacrifice taken away and 1,290 days later the abomination of desolation.
And I heard, but I understood not: then said I, O my master, what shall be the end of these things? And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.
Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand.
And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days.
Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
(Dan 12:8-12)
This is known as Yaacov's trouble (Jeremiah 30:7) and the tribulation period. After the abomination of desolation and before Messiah returns, there is a 45 day period that will be shortened by The Father. This 45 day time period is referred to as Great Tribulation.
Matthew 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
45 days after the abomination of desolation is the scheduled return of Yeshua, HOWEVER, the days are shortened, by The FATHER, and only The FATHER knows the exact day He will send Yeshua to rescue His people, save them from destruction when it seems hopeless, as in the days of the exodus from Egypt and the pursuit of Pharoah and his armies.
Matthew 24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Matthew 24:36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
Folks, please remember the words of Yeshua, which is to this generation and you if you believe His report;
And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares.
For as a snare shall it come on all them that dwell on the face of the whole earth.
Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
(Luke 21:34-36, KJV)
Not by power, nor by might, but by My Ruach says יהוה!
We are an international community waiting, watching and praying to see the 2 witnesses when they arrive. We hope to greet them, show them that they are appreciated, and, if it be possible or necessary, to be a service to them in any way should they require any type of assistance.
