The practice of building splendid edifices of cedar was not confined to Solomon; the great nobles and princes who lived in Jerusalem, the high officers, and his favourites, all followed his example. With the wealth that streamed into the land through the opening of three important channels, the love of show, which spread from the king to the higher classes, could be freely gratified. Phœnician merchants of high standing, who carried on a large wholesale trade, money-changers, men of wealth who lent money on interest, now settled in Jerusalem. They composed a special corporation or guild, and were under the protection of the treaty between Solomon and Hiram. They were permitted to live according to their own laws, and were even allowed to practise their religious or, rather, idolatrous rites. The three great sources of wealth were the _Powerful Position of the State_, the _Alliance with Egypt_, and the _Indian Trade_. Those princes who had entered into treaties with David confirmed them with his successor, and other potentates sought his friendship. On swearing allegiance, all these princes and nations sent the customary tribute and rich gifts, such as gold and silver vessels, valuable garments, spices, horses and mules. The alliance with Egypt was also the source of considerable additions to the national wealth, as that kingdom furnished horses to the mountainous districts, and war chariots, which were in great demand in foreign parts. The princes of Aram and of the territories on the Euphrates who had formerly procured their horses and chariots from Egypt, were to buy these war materials from Solomon's merchant guild. The latter established a station for his own riders and horses on the plain not far from the sea. He kept twelve thousand horses and fourteen hundred war chariots (each drawn by two horses), and for these he erected spacious buildings, containing four thousand stalls. Solomon's greatest gains, however, were acquired in trade with India. To the Phœnicians the journey to this distant country was attended with insuperable difficulties, so long as the country near the Red Sea was rendered unsafe by the uncivilised and predatory bands that dwelt there. By his alliance with Hiram, Solomon had opened up a safer and nearer route to India. The strip of land extending from the southern border of Judah to the eastern coast of the Red Sea, the Points Elath and Eziongeber, had been rendered accessible. The caravans with their loaded camels could proceed in safety from Jerusalem and from the coast to the northern point of the Red Sea. At Hiram's suggestion, Solomon had a fleet of strong and large ships (ships of Tarshish) built, and equipped on the coast at Eziongeber. Hiram sent his most skilful sailors, who knew the route thoroughly, to man the vessels. Israelites of the tribes of Asher and Zebulun, who lived on the coast and were acquainted with the sea, were also employed.
