(ii) Ra` anan (7488) - from an unused root meaning to be green; verdant; by analogy, new; figuratively, prosperous:
The words for green normally describe vegetation of some type. It is used of pastures <Ps. 23:2>; herbage <2 Kin. 19:26>; trees in general <Deut. 12:2; Luke 23:31; Rev. 8:7>; the marriage bed (in a figurative sense, <Song 1:16>); a hypocrite compared to a papyrus plant <Job 8:16>; and grass <Mark 6:39>. A word meaning "greenish" describes plague spots <Lev. 13:49; 14:37> as well as the color of gold.
