The beginning of sorrows (false labor pangs) is from the Olivet Discourse, not Revelation.
The timing of the beginning of sorrows is before the opening of the seven sealed scroll in Revelation 6-7.[/QUOTE
Have you ever read Matthew 24?
When we compare the seven seals of Rev.ch 6 with Mat.ch 24 then we can see that the beginning of sorrows is somewhere in the first three seals.
because the fourth seal reveals the massacre of all (if he finds them)who will not take the mark and worship the beast within his kingdom (a quarter of the earth) (by the dragon) Rev.13
Rev 6:8 And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over
the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
Rev 12:12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Rev 9:1 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
Rev 9:2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
Rev 9:3 And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
Rev 9:4 And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.
Rev 9:5 And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
Rev 9:6 And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
Mat 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.
Mat 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.
