'Cock' in the Bible

Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.

Then began he to curse and to swear, saying, I know not the man. And immediately the cock crew.

And Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly.
