'Unto' in the Bible

that the fellowship of thy faith may become effectual, in the knowledge of every good thing which is in you, unto Christ.

whom I would fain have kept with me, that in thy behalf he might minister unto me in the bonds of the gospel:

I Paul write it with mine own hand, I will repay it: that I say not unto thee that thou owest to me even thine own self besides.

Having confidence in thine obedience I write unto thee, knowing that thou wilt do even beyond what I say.

But withal prepare me also a lodging: for I hope that through your prayers I shall be granted unto you.
