9. The Abomination of Desolation Spoken of by Daniel the Prophets will come to pass.
Verses
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),
16 Then let them which be in Judæa flee into the mountains:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
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.
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.
To the prophet Joseph Smith, these verses were given more clarity through revelation as follows:
Joseph Smith - Matthew 1:32-34
32 And again shall the abomination of desolation, spoken of by Daniel the prophet, be fulfilled.
33 And immediately after the tribulation of those days, the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of heaven shall be shaken.
34 Verily, I say unto you, this generation, in which these things shall be shown forth, shall not pass away until all I have told you shall be fulfilled.
Basically it is predicted that the Abomination of Desolation would occur twice. The first occurrence happened in 70 A.D. when the Jews were scattered and destroyed in Jerusalem. The second occurrence will happen when Jerusalem is again besieged right before Jesus comes back and sets his foot down upon the Mount of Olives and saves the Jews in their plight. This more famously known as the the time of the battle of Armageddon. The shortening of those days, I believe, applies to the second Abomination of Desolation and it will be Jesus who brings those days to be shortened by his coming and setting his foot upon the Mount of Olives.
Nope. The first abomination of desolation was during the reign of Antiochus IV Epiphanies around 167 BC. He was keen to Hellenize the Jews so he forbid circumcision, defiled the temple with pagan gods and pig sacrifices. This is where Joseph Smith destroyed his credibility.
