6 Then the leaders of fathers' houses made their freewill offerings, as did also the leaders of the tribes, the commanders of thousands and of hundreds, and the officers over the king's work. 7 They gave for the service of the house of God 5,000 talents and 10,000 darics[1] of gold, 10,000 talents of silver, 18,000 talents of bronze and 100,000 talents of iron. 8 And whoever had precious stones gave them to the treasury of the house of the Lord, in the care of Jehiel the Gershonite. 9 Then the people rejoiced because they had given willingly, for with a whole heart they had offered freely to the Lord. David the king 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.
