John 5:12-15

Then they asked him, “Who is the man who told you to pick up your mat and walk?” But the man who had been healed did not know who it was, because there were many people in that place, and Jesus had left. Later, Jesus found the man at the Temple and said to him, “See, you are well now. Stop sinning so that something worse does not happen to you.” Then the man left and told his people that Jesus was the one who had made him well.
