John 5:12-15

They asked him, “Who is the Man who told you, ‘Pick up your pallet and walk’?” Now the man who had been healed did not know who it was, for Jesus had slipped away [unnoticed] since there was a crowd in that place. Afterward, Jesus found him in the temple and said to him, “See, you are well! Stop sinning or something worse may happen to you.” The man went away and told the Jews that it was Jesus who had made him well.
