Proverbs 15:4, 7, Tongues: Sound or Sick?
Both proverbs refer to speech, good or bad. The wholesome (sound 14:30) tongue that is a tree of Life (4) parallels the lips of the wise that disperse knowledge (7). The perverseness that is a breach of the spirit (4) has its counterpart in the heart of the foolish [that] does not so (7), that is, disperse knowledge. Note the relation between the lips and the heart in v.7. A wholesome tongue is a healed tongue that produces life. It’s lips, therefore, are wise lips. The word perverse only appears twice in the Hebrew Bible, and both times in Proverbs (11:3). It means to be twisted, or crooked. It is something out of line or even treacherous. Thus the scene is set. Are your lips sound or sick?
