John 5:12-15 NIV

[12] So they asked him, “Who is this fellow who told you to pick it up and walk?” [13] The man who was healed had no idea who it was, for Jesus had slipped away into the crowd that was there. [14] Later Jesus found him at the temple and said to him, “See, you are well again. Stop sinning or something worse may happen to you.” [15] The man went away and told the Jewish leaders that it was Jesus who had made him well.
