'Cock' in the Bible

But he said, I have no knowledge of him, or of what you are saying: and he went out into the doorway; and there came the cry of a cock.

And in the same minute, the cock gave a second cry. And it came to Peter's mind how Jesus had said to him, Before the cock's second cry, you will say three times that you have no knowledge of me. And at this thought he was overcome with weeping.
