Gracious words are a honeycomb,
sweet to the soul and healing to the bones.
(Proverbs 16:24)

Even the word "honeycomb" brings peaceful visions to my mind while imagining the bees miraculously building their honeycomb in perfect hexagons.  Only God could have orchestrated such a work of nature.  This word, and of course, a million more along these lines, brings a calmness to the soul that is truly healing.
