'Cock' in the Bible

"I solemnly tell you," replied Jesus, "that to-day--this night--before the cock crows twice, you yourself will three times disown me."

But he denied it, and said, "I don't know--I don't understand--What do you mean?" And then he went out into the outer court. Just then a cock crowed.

No sooner had he spoken than a cock crowed for the second time, and Peter recollected the words of Jesus, "Before the cock crows twice, you will three times disown me." And as he thought of it, he wept aloud.
