2 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. 3 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: 4 three thousand talents of gold, of the gold of Ophir, and seven thousand talents of refined silver, for overlaying the walls of the house, 5 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?" 6 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. 7 They gave for the service of the house of God five thousand talents and ten thousand darics of gold, ten thousand talents of silver, eighteen thousand talents of bronze, and one hundred thousand talents of iron.

Commentary on 1 Chronicles 29:1-9
(Read 1 Chronicles 29:1-9)
What is done in works of piety and charity, should be done willingly, not by constraint; for God loves a cheerful giver. David set a good example. This David offered, not from constraint, or for show; but because he had set his affection to the house of God, and thought he could never do enough towards promoting that good work. Those who would draw others to good, must lead the way themselves.
