John 5:10-13

So the Jews said to the man who had been healed, “It is the Sabbath, and it is not lawful for you to take up your bed.” But he answered them, “The man who healed me, that man said to me, ‘Take up your bed, and walk.’” They asked him, “Who is the man who said to you, ‘Take up your bed and walk’?” Now the man who had been healed did not know who it was, for Jesus had withdrawn, as there was a crowd in the place.
