'Deny' in the Bible

and he confessed and did not deny, and confessed -- 'I am not the Christ.'

You do not know Him, but I know Him perfectly; and were I to deny my knowledge of Him, I should resemble you, and be a liar. On the contrary I do know Him, and I obey His commands.

Jesus answered him, 'Thy life for me thou wilt lay down! verily, verily, I say to thee, a cock will not crow till thou mayest deny me thrice.'
