29:9 Then the people rejoiced, for that they offered willingly, because with {f} perfect heart they offered willingly to the LORD: and David the king also rejoiced with great joy.
(f) That is, with good courage and without hypocrisy.
29:9 Rejoiced - Because this was both an effect of God's grace in them, an eminent token of God's favour to them, and a pledge that this long - desired work, would receive a certain and speedy accomplishment. Great joy - To see the work, which his heart was so much set upon, likely to go on. It is a great reviving to good men when they are leaving the world, to see those they leave behind zealous for the work of God.
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.
