'Denying' in the Bible

But again he denied it. And after a little while the bystanders were again saying to Peter, “Surely you are one of them, for you are a Galilean too.”

And Jesus said, “Who is the one who touched Me?” And while they were all denying it, Peter said, “Master, the people are crowding and pressing in on You.”

But false prophets also arose among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves.
