My root was spread out by the waters, and the dew lay all night upon my branch. My root was spread out by the waters - A metaphor taken from a healthy tree growing beside a rivulet where there is plenty of water; which in consequence flourishes in all seasons; its leaf does not wither, nor its fruit fall off. See Psalms 1:3; Jeremiah 17:8.
