So how could I help but think of Nan C. Merrill's version of this psalm in her book, Psalms for Praying, in which she mixes paraphrase with faith-filled invention, and presents to us what I find to be deeply inspiring poetry:
Behold, how good and pleasant it is
when brothers and sisters
dwell in unity!
It is like vistas seen from
atop a mountain one has climbed...
Or like the stillness of a sunset
after a long day's work.
It is like a shimmering rainbow,
breaking through a summer rain.
When (people) dwell in harmony,
the star of Truth appears!
