[375] Now when the king had said this, he left off; but gave the description and pattern of the building of the temple in the sight of them all to Solomon: of the foundations and of the chambers, inferior and superior; how many they were to be, and how large in height and in breadth; as also he determined the weight of the golden and silver vessels: moreover, he earnestly excited them with his words to use the utmost alacrity about the work; he exhorted the rulers also, and particularly the tribe of Levi, to assist him, both because of his youth, and because God had chosen him to take care of the building of the temple, and of the government of the kingdom. He also declared to them that the work would be easy, and not very laborious to them, because he had prepared for it many talents of gold, and more of silver, with timber, and a great many carpenters and stone-cutters, and a large quantity of emeralds, and all sorts of precious stones; and he said, that even now he would give of the proper goods of his own dominion two hundred talents, and three hundred other talents of pure gold, for the most holy place, and for the chariot of God, the cherubim, which are to stand over and cover the ark. Now when David had done speaking, there appeared great alacrity among the rulers, and the priests, and the Levites, who now contributed and made great and splendid promises for a future Contribution; for they undertook to bring of gold five thousand talents, and ten thousand drams, and of silver ten thousand talents, and many ten thousand talents of iron; and if any one had a precious stone he brought it, and bequeathed it to be put among the treasures; of which Jachiel, one of the posterity of Moses, had the care.
