After the supper, Jesus and His eleven disciples crossed the Brook of Cedron, Valley of Kidron, and they gathered in the
cave of Gethsemane, where Jesus said to them: "You will all betray me this night." When Peter declared that he would not fail Him, Jesus looked at him and said: "Before the cock crows, you will deny me three times" (John XIII).
