1 Chronicles 29:1

We may here observe, I. How handsomely David spoke to the great men of Israel, to engage them to contribute towards the building of the temple. It is our duty to provoke one another to love and to good works, not only to do good ourselves, but to draw in others to do good too as much as we can. There were many very rich men in Israel; they were all to share in the benefit of the temple, and of those peaceable days which were to befriend the building of it; and therefore, though David would not impose on them, as a tax, what they should give towards it, he would recommend the present as a fair occasion for a free-will offering, because what is done in works of piety and charity should be done willingly and not by constraint; for God loves a cheerful giver. 1. He would have them consider that Solomon was young and tender, and needed help; but that he was the person whom God had chosen to do this work, and therefore was well worthy their assistance. It is good service to encourage those in the work of God that are as yet young and tender. 2. That the world was great, and all hands should contribute to the carrying of it on.
