'End' in the Bible

When you hear of wars and rumors of wars, do not be frightened; those things must take place; but that is not yet the end.

You will be hated by all because of My name, but the one who endures to the end, he will be saved.

And then He will send forth the angels, and will gather together His elect from the four winds, from the farthest end of the earth to the farthest end of heaven.
