Peter having denied You three times, straightway recalled the words You said to him, but he brought to You tears of repentance, saying: “God have mercy on me, and save me.”
I do not know Him… Immediately, while he was still speaking, the rooster crowed. And the Lord turned and looked at Peter. Then Peter remembered the word of the Lord, how He has said to him, “Before the rooster crows, you will deny Me three times.” So Peter went out and wept bitterly.
It has been described that the face of Saint Peter seemed to be inflamed with tears. Every time he heard in his memory the sweet voice of his Lord Jesus Christ, and when he thought about how he denied Him, Saint Peter would weep with tender emotion. He always carried a towel in his bosom to wipe his tears, and every time he heard a rooster crow in the night he would rise up and Pray.
