'Cock' in the Bible

"In solemn truth I tell you," replied Jesus, "that this very night, before the cock crows, you will three times disown me."

Then with curses and oaths he declared, "I do not know the man." Immediately a cock crowed,

and Peter recollected the words of Jesus, how He had said, "Before the cock crows you will three times disown me." And he went out and wept aloud, bitterly.
