The first several chapters of Isaiah are about the same wicked and perverse generation whose judgment Jesus speaks of in the Olivet Discourse, and Revelation (a book of the divorce of unfaithful wife Israel (wicked tenants in the parable), in favor of the bride of Christ, the church (the new Jerusalem, the holy Mountain, the redeemed of the Lord, the sought out, the city not forsaken, the heavenly Jerusalem, zion, those enrolled in heaven).
Isaiah 2:
19 And people shall enter the caves of the rocks
and the holes of the ground,[b]
from before the terror of the Lord,
and from the splendor of his majesty,
when he rises to terrify the earth.
This is the same event in Revelation 6:
12 When he opened the sixth seal, I looked, and behold, there was a great earthquake, and the sun became black as sackcloth, the full moon became like blood, 13 and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale. 14 The sky vanished like a scroll that is being rolled up, and every mountain and island was removed from its place. 15 Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave[d] and free, hid themselves in the caves and among the rocks of the mountains
JESUS in Luke 23 applied Isaiah to the coming judgment of Jerusalem:
28 But turning to them Jesus said, “Daughters of Jerusalem, do not weep for me, but weep for yourselves and for your children. 29 For behold, the days are coming when they will say, ‘Blessed are the barren and the wombs that never bore and the breasts that never nursed!’ 30 Then they will begin to say to the mountains, ‘Fall on us,’ and to the hills, ‘Cover us.’
This is the same event in the Olivet discourse:
29 “Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.
That Jesus said would happen in THAT generation:
34 Truly, I say to you, this generation will not pass away until all these things take place.
(And “before some of you standing here taste death,” and “before you make it through all the towns of Israel”)
Revelation is about judgment on the great harlot Jerusalem that killed Jesus, the “city where our Lord was slain,” the city “responsible for the blood of the prophets.”
Jesus: “Therefore I send you prophets and wise men and scribes, some of whom you will kill and crucify, and some you will flog in your synagogues and persecute from town to town,” “35 so that on you may come all the righteous blood shed on earth, from the blood of righteous Abel to the blood of Zechariah the son of Barachiah,[a] whom you murdered between the sanctuary and the altar.”
Jerusalem was ALREADY trampled by the gentiles. The priesthood, genealogies, and law, are ALREADY destroyed. Jerusalem WAS surrounded by armies. The 1260 days of terror ALREADY happened. The city was ALREADY split into 3 parts. 100-pound stones were ALREADY thrown into the city. The army with Apollo as their god ALREADY sieged Jerusalem.
And it all happened by ALL the deadlines Jesus gave.
And Revelation was written before AD 70. It TELLS you that.
