'End of the World' in the Bible

Their line is gone out through all the earth, And their words to the end of the world. In them hath he set a tabernacle for the sun,

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

As therefore the tares are gathered up and burned with fire; so shall it be in the end of the world.

So shall it be in the end of the world: the angels shall come forth, and sever the wicked from among the righteous,

And as he sat on the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what'shall be the sign of thy coming, and of the end of the world?

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

Ye adulteresses, know ye not that the friendship of the world is enmity with God? Whosoever therefore would be a friend of the world maketh himself an enemy of God.
