No they are different the one in revelation 7 is “the great tribulation” which is on the saints
The one in the Olivit discourse is “a great tribulation” which is on Israel there are most than one
The Olivet Discourse Great Tribulation is against Christians not Jews:
Who is persecuted in the great Tribulation? Jews or Christians?
The olivet discourse (Matthew):
Mat 24:4 And Jesus answered and said unto them, Take heed that no man deceive you.
Mat 24:5 For many shall come in my name, saying, I am Christ; and shall deceive many.
False Christ's are warned about.
Mat 24:9 Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations
for my name's sake.
These are Christians being delivered up not Jews. Hated because of Christ's name! This proves that Christ is talking about Christians when he says "you". He was also speaking to his Christian disciples.
Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
The gospel of the kingdom is about Christ and is delivered by Christians.
Mat 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, ( whoso readeth, let him understand: )
"Ye" are Christians.
So, the AoD is going to affect "all the world" and Christians are the targets! Christians are persecuted and murdered for the testimony of Christ and because they carry his name.
Mat 24:20 But pray ye that your flight be not in the winter, neither on the sabbath day:
"Ye" is still the same people, Christians.
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.
The elect are Christians not Jews per the context of this passage.
Mat 24:23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
Again, a warning about false Christs given to "you" which are Christians.
Mat 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Another reference to false Christ's and the Christian elect.
Mat 24:25 Behold, I have told you before.
Mat 24:26 Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
You=Christians and yet again another false Christ reference. There is a false Christ coming to deceive Christians and those not deceived will be delivered up, persecuted and killed.
Nothing about Jews at all because Jews are not the target of the Antichrist and tribulation.
Mat 24:27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.
Mat 24:28 For wheresoever the carcase is, there will the eagles be gathered together.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
And here is the second coming. The gathering of the elect by angels is another way to speak of the rapture and the rapture is only for Christians. Christians are the body of Christ, are the Church of Christ, and are the bride of Christ, targeted by the enemy during the Great Tribulation of Christian persecution.
Again, nothing about Jews in the religion of Judaism at all because they are not the target of the Antichrist and tribulation.
