How do you know? Please give Scripture references.
"We know that the Great Tribulation will be seven years long with three years of peace and safety."
That's odd - 7 years of tribulation includes "three years of peace and safety." Doesn't sound like 7 years of tribulation. Only 3 1/2 or 4 years of tribulation.
Which Scriptures teach you what you assert?
What "people in Israel" want to do has nothing to do with Bible prophecy. See my posts #83 & #89.
Daniel 9:27 (KJV) And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make [it] desolate, even until the consummation, and that determined shall be poured upon the desolate.
So this tells us that the Great Tribulation shall last seven years and that in the midst of the seven years the temple sacrifice and oblation shall be ordered stopped as the temple will be defiled.
Jeremiah 30:7 (KJV) Alas! for that day [is] great, so that none [is] like it: it [is] even the time of Jacob's trouble; but he shall be saved out of it.
Revelation 12:6 (KJV) And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred [and] threescore days. (Petra?)
Revelation 13:11-18 (KJV) And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon. And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed. And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, And deceiveth them that dwell on the earth by [the means of] those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live. And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number [is] Six hundred threescore [and] six.
What Jesus said:
Matthew 24:15-22 (KJV) 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 Then let them which be in Judaea flee into the mountains: Let him which is on the housetop not come down to take any thing out of his house: Neither let him which is in the field return back to take his clothes. And woe unto them that are with child, and to them that give suck in those days! But pray ye that your flight be not in the winter, neither on the sabbath day: For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
