'End of the World' in the Bible

The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.

As therefore the tares are gathered together, and burnt in the fire; so shall it be in the end of the world:

So shall it be at the end of the world: the angels shall come forth, and separate the wicked from among the righteous;

And when He was got to the mount of olives, the disciples came to Him in private and said, Tell us when these things shall be, and what shall be the sign of thy coming, and of the end of the world.

and of the holy Ghost, and teaching them to observe all things whatsoever I have commanded you: and lo, I am with you always, even to the end of the world. Amen.

Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity to God? whosoever therefore will be a friend of the world becomes an enemy of God.
