The first story:
Jesus knew that they had come for him to kill him, so God took him to heaven and save him, God made the one who betrayed Jesus and his position told to look like Jesus, so they beat him though death.
The second story:
Jesus knew, and who wants to kill him coming, so he asked his followers who are willing to take me somewhere, he will be with me in paradise. Therefore, the youngest guy volunteered to take his place, he found he was young, so he repeated his question again, his followers, the young guy has taken the initiative of the. Then he repeated the problem and the young guys still want to give yourself to help him. So he took the form of Jesus, and take a crucified instead. This may be who says: "My God! My God! Why do not you forsaken me", in fact, that guy who volunteers to help Jesus.
