Sorry about that.
I believe the 42 months refers specifically to our Saviors' ministry because the tribulation, or adversity He faced was never or ever will be seen on earth again.
Not because other people haven't faced unjust torture, but because of Who was being sinned against.
The Bible mentions "the time of Jacobs trouble" as a time when Gods' people are suffering and delivered by the Messiah.
Now here's a key. Jacob suffered because of following God, which is exactly what the Messiah said would happen to His followers.
His followers (whether OT or NT) are members of His body.
For the body is not one member but many......And whether one member suffer all the members suffer with it; 1Cor.12:14,26 KJV
he that rejecteth you rejecteth me and he that rejecteth me rejecteth him that sent me. Lk.10:16 ASV
We see evil happening all around the world but since the Messiah came, gentile nations learned why. But the main point is scripture only makes sense "in Christ",
that the blood of all the prophets which has been poured out from the foundation of the world may be required of this generation, Lk.11:50 KJV
No one can be punished for murdering someone they never met. Jesus is speaking to people who lived humdreds of years after the prophets.
It's senseless, unless the prophets were somehow one body.
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.
Jesus spoke this as the disciples gathered to Him on the mount of Olives and asked Him three questions, "Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?"
The first thing Jesus told them about was the coming destruction of the Temple, which happened in 70AD. From vs. 3-14 continued telling them all those things that must come first before He returns. Vs. 15 Jesus speaks of the abomination of deslolation spoken of by Daniel the prophet as we can study this in Daniel 7-9, going in greater detail in Rev 13, 17, 18.
Jesus ministry here on earth did lasted around 3 1/2 years, but the 3 1/2 years in the end of days, abomination of desolation) is that of a NWO or better known as a Luciferian system comprised of economic, political, militant, environmental and false religious system which is the beast out of the sea who gives its power and authority to the beast out of the earth, Rev 13.
This is how I understand the times of Jacobs trouble.
Jeremiah was told to write this prophecy in a book of what God was about to give him of future events. Here we have this portion of the book of Jeremiah as prophecy given for a future state of Judah and Israel. Rachel would weep for her children in the distress they have always been in, but will receive her peace in the end of days as all will when Christ returns.
Jeremiah 30 vs. 1, 2 starts out with the Lord speaking to Jeremiah about Judah an Israel. Vs 3 the Lord promises that one day in the future as the day will come that He will bring Judah and Israel back to the land He had promised to their forefathers. Vs. 5 describes a time of great fear and trembling. Vs. 6 describes this time in a way that pictures men going through the pains of childbirth, meaning great agony. Vs. 7 For that day is great so that no other day will ever be like it. This is a reference to Matthew 24:21; Rev 7:1-8. But, there is hope for Judah and Israel for though this is called the time of Jacob's trouble the Lord promises He will save Jacob (referring to Judah and Israel, not literally Jacob) out of this time of great trouble, Rev 19:11-21. Vs. 8 It shall come to pass in that day (in that day means a future day) says the Lord that He will break his yoke from off their necks and will burst thy bonds and strangers shall no more serve themselves of him. His yoke is that of Satan who for now controls the evil principalities of this world that even today until Christ returns persecutes God's people. Vs. 9 But they shall serve the Lord their God and David their King, meaning Jesus whom God will raise up (resurrection) unto them. Vs 10, 11 the Lord says, I will surely save you out of a distant place, your descendants from the land of their exile. Jacob will again have peace and security and no one will make him afraid. I am with you and will save you declares the Lord.
All of this happens on the last day when Christ returns and makes an end to all abominations here on earth that have come against His people as no one will then be held by the stronghold of Satan anymore.
2Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
2Peter 3:11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
2Peter 3:12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
2Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
