'End' in the Bible

And if Satan rise up against himself, and is divided, he cannot subsist, but has an end.

But when ye shall hear of wars and rumours of wars, be not disturbed, for this must happen, but the end is not yet.

And ye will be hated of all on account of my name; but he that has endured to the end, he shall be saved.

and then shall he send his angels and shall gather together his elect from the four winds, from end of earth to end of heaven.
