'Unto' in the Bible

But we desire earnestly that each one of you shew the same diligence to the full assurance of hope unto the end;

And they shall not teach each his fellow-citizen, and each his brother, saying, Know the Lord; because all shall know me in themselves, from the little one among them unto the great among them.

Ye have not yet resisted unto blood, wrestling against sin.

So that, taking courage, we may say, The Lord is my helper, and I will not be afraid: what will man do unto me?
