john 5:14 Afterward Jesus findeth him in the temple, and said unto him, Behold, thou art made whole: sin no more, lest a worse thing come unto thee. - Free Bible Online

      14. findeth him in the temple--saying, perhaps, "I will go into Thy house with burnt offerings, I will pay my vows which my lips have uttered and my mouth hath spoken when I was in trouble" (Ps 66:13, 14). Jesus, there Himself for His own ends, "findeth him there"--not all accidentally, be assured.
      sin no more, &c.--a glimpse this of the reckless life he had probably led before his thirty-eight years' infirmity had come upon him, and which not improbably had brought on, in the just judgment of God, his chronic complaint. Fearful illustration this of "the severity of God," but glorious manifestation of our Lord's insight into "what was in man."
