'Least' in the Bible

If to others I am not an Apostle, at least I am one to you: for the fact that you are Christians is the sign that I am an Apostle.

To the feeble, I was as one who is feeble, so that they might have salvation: I have been all things to all men, so that some at least might have salvation.

For I am the least of the Apostles, having no right to be named an Apostle, because of my cruel attacks on the church of God.
