John Gill's Exposition of the Whole Bible
1 Chronicles 29:4
Even three thousand talents of gold,.... Which, according to Scheuchzer c, amount to 36,660,000 ducats of gold; and, according to Brerewood d, to 13,500,000 pounds of our money:
of the gold of Ophir; which was reckoned the best gold; not Ophir in India, which was not known till Solomon's time, but in Arabia, as Bochart e has shown; so Eupolemus f, an Heathen writer, says, that David having built ships at Achan, a city of Arabia, sent miners to Urphe (supposed to be the same with Ophir) in the island of the Red sea, abounding with gold, and from thence fetched it, See Gill on 1Ki 9:28, and that he was able to give so great a sum out of his own substance, Dr. Prideaux g thinks, can only be accounted for by his great returns from this traffic; since these 3000 talents, according to him, amounted to 21,600,000 pounds sterling:
and seven thousand talents of refined silver; amounting, according to Scheuchzer h, to 31,500,000 imperials, or rix dollars; and, according to Brerewood i, to 2,625,000 pounds of our money:
to overlay the walls of the houses withal; the gold was to overlay the walls of the holy and most holy place, the silver to overlay the walls of the chambers built around the temple.
