'Nay' in the Bible

Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.

What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.

Nay, in all these things we are more than conquerors through him that loved us.

Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?
