 ivory
      n 1: a hard smooth ivory colored dentine that makes up most of

 Ivory
    (Heb. pl. shenhabbim, the "tusks of elephants") was early used
    in decorations by the Egyptians, and a great trade in it was
    carried on by the Assyrians (Ezek. 27:6; Rev. 18:12). It was
    used by the Phoenicians to ornament the box-wood rowing-benches
    of their galleys, and Hiram's skilled workmen made Solomon's
    throne of ivory (1 Kings 10:18). It was brought by the caravans
    of Dedan (Isa. 21:13), and from the East Indies by the navy of
    Tarshish (1 Kings 10:22). Many specimens of ancient Egyptian and
    Assyrian ivory-work have been preserved. The word _habbim_ is
    derived from the Sanscrit _ibhas_, meaning "elephant," preceded
    by the Hebrew article (ha); and hence it is argued that Ophir,
    from which it and the other articles mentioned in 1 Kings 10:22
    were brought, was in India.
