'Void' in the Bible

void of understanding, faithless, without natural affection, unmerciful;

What then? If some did not believe or were unfaithful [to God], their lack of belief will not nullify and make invalid the faithfulness of God and His word, will it?

Do we then make void the law through faith? God forbid: yea, we establish the law.

For if they which are of the law be heirs, faith is made void, and the promise made of none effect:

But I say, Did Israel not know? First Moses saith, I will provoke you to jealousy with that which is no nation, With a nation void of understanding will I anger you.
