Two tribulations, one great [Strong's 3173], in Matthew and Revelation, but non-apostles Luke & Mark don't mention the 1st because they were part of the antichrist spirit that produced it: the KJV again MISTRANSLATES to hide the truth!

Tribulation #1, target: Followers of the Way

⁹ Then shall they deliver you up to be afflicted [TRIBULATION, thlipsin Strong's 2347] , and shall kill you: and ye shall be hated of all nations for my name’s sake.

¹⁰ And then shall many be offended, and shall betray one another, and shall hate one another.

Matthew 24

⁸ And unto the angel of the ecclesia in Smyrna write; These things saith the first and the last, which was dead, and is alive;

⁹ I know thy tribulation [thlipsin Strong's 2347], and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.

¹⁰ Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation [thlipsin Strong's 2347] ten days: be thou faithful unto DEATH, and I will give thee a crown of life.

Revelation 2

Ten days: Historical fact, 10 years intense persecution by Rome (303 A.D. – 313 A.D.) leading to legalized Christianity, i.e. the establishment of the Roman Catholic Church and forced acceptance of ‘the Bible’, which combines Pharisee doctrine with the Word. Legalized Christianity is nothing but Pagan worship in disguise…EASTER plus the ancient winter Solstice celebration now called CHRISTMAS.

Followers of the Way were killed…not left to celebrate the edict of Milan!

Tribulation #2,  target: Followers of Jezebel — brace yourself for Albert Pike’s WWWIII, Christianity (Harlot & daughters) vs. Islam

“For then shall be GREAT [megalē Strong's 3173] TRIBULATION [thlipsis Strong's 2347], such as was not since the beginning of the world to this time, no, nor ever shall be.” Matthew 24:21

²² Behold, I will cast her into a bed, and them that commit adultery with her into GREAT [megalēn Strong's 3173] TRIBULATION [thlipsin Strong's 2347], except they repent of their deeds.

²³ And I will kill her children with DEATH; and all the ecclesia shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.

Revelation 2

“And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of THE [tēs Strong's 3588] GREAT [megalēs Strong's 3173] TRIBULATION [thlipseōs Strong's 2347], and have washed their robes, and made them white in the blood of the Lamb.” Revelation 7:14
