John 5:11-13 (New International Version)

 ¹¹But he replied, "The man who made me well said to me, 'Pick up your mat and walk.' "

 ¹²So they asked him, "Who is this fellow who told you to pick it up and walk?"

 ¹³The man who was healed had no idea who it was, for Jesus had slipped away into the crowd that was there.
