1 Kings 10:10

Strabo relates that the Sabaeans were enormously wealthy, and used gold and silver in a most lavish manner in their furniture, their utensils, and even on the walls, doors, and roofs of their houses. That the gold of Sheba should be given to Solomon was prophesied by the writer of Psalms 72 (see the marginal reference). The immense abundance of spices in Arabia, and especially in the Yemen or Sabaean country, is noted by many writers. According to Strabo, the spice-trade of Arabia was in the hands of two nations, the Sabaeans and the Gerrhaeans. The spices in which they dealt seem to have been only in part the produce of Arabia itself; some of the most important kinds, as the cinnamon and the cassia, must have been imported from India, since Arabia does not yield them. The chief precious stones which Arabia now yields are the onyx and the emerald. Anciently she is said to have produced other gems. Pearls, too, were readily procurable in Arabia from the Persian Gulf fishery.
