'Denying' in the Bible

Jesus said, “Who touched Me?” While they all were denying it, Peter [and those who were with him] said, “Master, the people are crowding and pushing against You!”

Women received back their dead by resurrection; and others were tortured [to death], refusing to accept release [offered on the condition of denying their faith], so that they would be resurrected to a better life;

But [in those days] false prophets arose among the people, just as there will be false teachers among you, who will subtly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction on themselves.
