'Except' in the Bible

that is not another, except there be certain who are troubling you, and wishing to pervert the good news of the Christ;

But I didn’t see any of the other apostles except James, the Lord’s brother.

For if anyone thinks he is something [special] when [in fact] he is nothing [special except in his own eyes], he deceives himself.

But as for me, I will never boast about anything except the cross of our Lord Jesus Christ. The world has been crucified to me through the cross, and I to the world.
