Daniel 12.1-3

And at that time there will arise Michael, the great prince, who stands for the sons of your people; and there shall begin a time of anguish, such as has never been among the nations until that time. And at that time, your people shall be saved, all who shall be found written in the book. And many of those who sleep in the dust of the ground will be awoken, some into eternal life, and some into shame, that they may be always contempted. And those who were taught shall shine as the splendor of the firmament; and those who have taught many to righteousness will be like stars in everlasting eternities.

Hebrews 10.11-25

And indeed every priest attends to the holy things day by day, and offers often the very same sacrificial victims, which can never bear away sins. But he, indeed, offering a single sacrifice for sins forever, sits at God’s right, that which remains awaiting for his enemies to be given him as a stool for his feast. For by a single offering he has rendered those who shall be made holy perfect forever. For also the holy spirit itself shall bear witness to us, when it was said before,

This is the testament which I shall institute
with them after those days, —says the Lord:
I shall give my laws upon their hearts,
and upon their minds I shall inscribe them;
and their sins and iniquity
I shall no further bring to memory.

Now where there is remission of these things, there is no longer an offering for sin.

Therefore, brothers, being that we have the freedom of entering into the holy place in the blood of Jesus, by the new and living way which he has dedicated to us, through the veil—that is to say, by his flesh—and that we have a great priest set over the house of God, we ought to come with true heart in trueness of faith, hearts sprinkled from evil conscience, and bodies washed with pure water. We ought to grasp the confession of hope unwavering—for God, who promised, is faithful—and to consider each other that we may provoke ourselves to love and good works, not deserting the gathering together among ourselves as is the manner of some, but exhorting each other, and so much more now that you see the day approaching.

Mark 13.1-8

And as he left the temple, one of his disciples said to him, “Teacher, see such stones and such buildings.”

And Jesus, answering, said to him, “Do you see these great buildings? There shall not be left stone upon stone, which will not be knocked down.”

And as he sat upon the Mount of Olives from the area of the temple, Peter, James, John and Andrew would question him secretly: “Tell us when these things will be? And what is the sign when all these things will be completed?”

And Jesus, answering them, began to say, “See that no one may deceive you. For many will come in my name, saying, ‘It is I’, and will deceive many. And when you hear of wars and rumors of wars, do not be disturbed. For these must be, but this is not yet the end. For one nation will rise up against another nation, and kingdom against kingdom. And there will be earthquakes in various places, and there will be famines and disturbances; these are the start of the pangs.”
