After Satan and his angels are cast out of heaven, into the earth, he will give power to the BEAST whose deadly wound was healed, and the False Prophet (Kings of Babylon). They will persecute (kill) Christ’s brethren (144,000) who died in him, and who speak the words of God. This time period is known as the Great Tribulation.

During the Great Tribulation, the Most High will give power to his Two Witnesses, and they will prophesy 3 ½ years (time, and times, and dividing of time; a thousand two hundred and threescore days; forty and two months).

Matthew 24:22: “And except those days” [A thousand two hundred and threescore days/forty and two months] “should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.”
