6 Then the leaders of the fathers' houses, leaders of the tribes of Israel, the captains of thousands and of hundreds, with the officers over the king's work, offered willingly. 7 They gave for the work 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. 8 And whoever had precious stones gave them to the treasury of the house of the Lord, into the hand of Jehiel the Gershonite. 9 Then the people rejoiced, for they had offered willingly, because with a loyal heart they had offered willingly to the Lord; and King David also rejoiced greatly.
Matthew Henry's Commentary on 1 Chronicles 29:6-9
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.
