'Acknowledge' in the Bible

For we write none other things unto you, than what ye read or acknowledge; and I trust ye shall acknowledge even to the end;

according as also ye did acknowledge us in part, that your glory we are, even as also ye are ours, in the day of the Lord Jesus;

So then from now on we acknowledge no one from an outward human point of view. Even though we have known Christ from such a human point of view, now we do not know him in that way any longer.
