'Nought' in the Bible

But it is not as though the word of God hath come to nought. For they are not all Israel, that are of Israel:

Let not him that eateth set at nought him that eateth not; and let not him that eateth not judge him that eateth: for God hath received him.

But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
