heath--In Psa 102:17; Isa 32:11; Hab 3:9, the Hebrew is translated, "bare," "naked," "destitute"; but as the parallel in Jer 17:8 is "tree," some plant must be meant of which this is the characteristic epithet (Jer 48:6, Margin), "a naked tree." ROBINSON translates, "the juniper tree," found in the Arabah or Great Valley, here called "the desert," south of the Dead Sea. The "heath" was one of the plants, according to PLINY (13.21; 16.26), excluded from religious uses, because it has neither fruit nor seed, and is neither sown nor planted. not see . . . good-- (Job 20:17). salt land-- (Deu 29:23), barren ground.
