'End' in the Bible

For in our letters we say no other things to you, but those which you are reading, and to which you give agreement, and, it is my hope, will go on doing so to the end:

And are not like Moses, who put a veil on his face, so that the children of Israel might not see clearly to the end of the present order of things:

So if any man is in Christ, he is in a new world: the old things have come to an end; they have truly become new.

Putting an end to reasonings, and every high thing which is lifted up against the knowledge of God, and causing every thought to come under the authority of Christ;

So it is no great thing if his servants make themselves seem to be servants of righteousness; whose end will be the reward of their works.
