References for 1 Chronicles 29:1
So I have provided for the house of my God, so far as I was able, the gold for the things of gold, the silver for the things of silver, and the bronze for the things of bronze, the iron for the things of iron, and wood for the things of wood, besides great quantities of onyx and stones for setting, antimony, colored stones, all sorts of precious stones, and marble in abundance.
Moreover, in addition to all that I have provided for the holy house, I have a treasure of my own of gold and silver, and because of my devotion to the house of my God I give it to the house of my God:
three thousand talents of gold, of the gold of Ophir, and seven thousand talents of refined silver, for overlaying the walls of the house,
and for all the work to be done by artisans, gold for the things of gold and silver for the things of silver. Who then will offer willingly, consecrating themselves today to the Lord?"
Then the leaders of ancestral houses made their freewill offerings, as did also the leaders of the tribes, the commanders of the thousands and of the hundreds, and the officers over the king's work.
