'Deny' in the Bible

And he said unto all, If any man would come after me, let him deny himself, and take up his cross daily, and follow me.

And he said, I tell thee, Peter, the cock shall not crow this day, until thou shalt thrice deny that thou knowest me.

And the Lord turned, and looked upon Peter. And Peter remembered the word of the Lord, how that he said unto him, Before the cock crow this day thou shalt deny me thrice.
