John 18:8-11

Jesus answered, I have told you that I am he: if therefore ye seek me, let these go their way: that the saying might be fulfilled, which he spake, Of them which thou gavest me have I lost none. Then Simon Peter having a sword drew it, and smote the high priest's servant, and cut off his right ear. The servant's name was Malchus. Then said Jesus unto Peter, Put up thy sword into the sheath: the cup which my Father hath given me, shall I not drink it?
