Mark 14:26-31, 50, 53-54, 66-72
And when they had sung a hymn, they went out to the Mount of Olives. And Jesus said to them, “You will all fall away, for it is written, ‘I will strike the shepherd, and the sheep will be scattered.’ But after I am raised up, I will go before you to Galilee.” Peter said to him, “Even though they all fall away, I will not.” And Jesus said to him, “Truly, I tell you, this very night, before the rooster crows twice, you will deny me three times.” But he said emphatically, “If I must die with you, I will not deny you.” And they all said the same.
…And they all left him and fled.
…And they led Jesus to the high priest. And all the chief priests and the elders and the scribes came together. And Peter had followed him at a distance, right into the courtyard of the high priest. And he was sitting with the guards and warming himself at the fire.
…And as Peter was below in the courtyard, one of the servant girls of the high priest came, and seeing Peter warming himself, she looked at him and said, “You also were with the Nazarene, Jesus.” But he denied it, saying, “I neither know nor understand what you mean.” And he went out into the gateway and the rooster crowed. And the servant girl saw him and began again to say to the bystanders, “This man is one of them.” But again he denied it. And after a little while the bystanders again said to Peter, “Certainly you are one of them, for you are a Galilean.” But he began to invoke a curse on himself and to swear, “I do not know this man of whom you speak.” And immediately the rooster crowed a second time. And Peter remembered how Jesus had said to him, “Before the rooster crows twice, you will deny me three times.” And he broke down and wept.
