Mark 14:72

And immediately the rooster crowed a second time. Then Peter remembered the word that Jesus had spoken to him: “Before the rooster crows twice, you will deny Me three times.” And he broke down and wept.

And the second time the cock crew. And Peter called to mind the word that Jesus said unto him, Before the cock crow twice, thou shalt deny me thrice. And when he thought thereon, he wept.
