'End' in the Bible

For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.

this first knowing, that there shall come in the latter end of the days scoffers, according to their own desires going on,

And that the world which then was came to an end through the overflowing of the waters.

Seeing then that all these things are coming to such an end, what sort of persons is it right for you to be, in all holy behaviour and righteousness,

Looking for and truly desiring the coming of the day of God, when the heavens will come to an end through fire, and the substance of the earth will be changed by the great heat?
