'Cock crowing' in the Bible

Jesus said to him, 'Verily I say to thee, that, this night, before cock-crowing, thrice thou wilt deny me.'

and Peter remembered the saying of Jesus, he having said to him -- 'Before cock-crowing, thrice thou wilt deny me;' and having gone without, he did weep bitterly.

watch ye, therefore, for ye have not known when the lord of the house doth come, at even, or at midnight, or at cock-crowing, or at the morning;

And he said, I tell thee, Peter, it shall not be the time of cockcrowing this day, before thou wilt thrice deny that thou knowest me.

whereupon the Lord turned about, and look'd upon Peter. then Peter remembred what the Lord had said to him, "before the cock-crowing you shall deny me thrice."

how he had said to him, Before cock-crowing, thou wilt deny me thrice. And Peter went out, and wept bitterly.
