'Deny' in the Bible

I know where thou dwellest, even where Satan's throne is; and thou holdest fast my name, and didst not deny my faith, even in the days of Antipas my witness, my faithful one, who was killed among you, where Satan dwelleth.

I know thy works (behold, I have set before thee a door opened, which none can shut), that thou hast a little power, and didst keep my word, and didst not deny my name.
