'Nay' in the Bible

But Paul said unto them, They have beaten us publicly, uncondemned, men that are Romans, and have cast us into prison; and do they now cast us out privily? Nay verily; but let them come themselves and bring us out.

and he said unto them, Did ye receive the Holy Spirit when ye believed? And they'said unto him, Nay, we did not so much as hear whether the Holy Spirit was given .
