'Denied' in the Bible

And he confessed, and denied not; but confessed, I am not the Christ.

Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.

And Simon Peter stood and warmed himself. They said therefore unto him, Art not thou also one of his disciples? He denied it, and said, I am not.

Peter then denied again: and immediately the cock crew.
