thi'-in (xulon thuinon): An aromatic wood described as sold in "Babylon" (Re 18:12, the King James Version margin "sweet wood"). It is the wood of the thya (thuia) tree, probably identical with Thuia articulata an evergreen tree growing in North Africa, resembling the cypress, which in Roman times was employed for making valuable furniture.
