'Cock' in the Bible

"I tell you, Peter," said Jesus, "that the cock will not crow to-day till you have three times denied that you know me."

"Man, I don't know what you mean," replied Peter. No sooner had he spoken than a cock crowed.

The Master turned and looked on Peter; and Peter recollected the Master's words, how He had said to him, "This very day, before the cock crows, you will disown me three times."
