Daniel 7:25: “And he" [The Little Horn/The False Prophet] "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" [The 144,000/Servants of God] "shall be given into his hand until a time and times and the dividing of time.” A time (one) and times (two) and the dividing of time (a half), or 3 ½ years, the time period of the Great Tribulation.
Revelation 11:3: “And I” [Christ] “will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days," [3 ½ years] "clothed in sackcloth.”
Revelation 13:5: “And there was given unto him"
[The BEAST whose deadly wound was healed] "a mouth
speaking great things and blasphemies; and power was given unto him to continue
forty and two
months.” The forty and two months or 3 ½ years, is the
time period of the Great Tribulation!
