Rosin
found only in Authorized Version, margin, Ezek. 27:17, Heb. tsori, uniformly rendered elsewhere "balm" (q.v.), as here in the text. The Vulgate has resinam, rendered "rosin" in the Douay Version. As used, however, by Jerome, the Lat. resina denotes some odoriferous gum or oil.
rosin
translucent, brittle, friable resin used for varnish and in manufacturing many products. It becomes sticky when warm and has a faint pinelike odour. Gum rosin consists of the residue obtained upon distillation of the oleoresin (a natural fluid) from pine trees (the volatile component is spirit of turpentine); wood rosin, obtained by solvent extraction of the stumps, is usually of a darker colour
