I Chronicles 29:18

And give unto Solomon my son a perfect heart to keep thy commandments, thy testimonies, and thy statutes,.... All the laws of God, moral, ceremonial, and judicial, even to observe them cordially and sincerely: and to do all those things; he had suggested to him particularly: and to build the palace for the which I have made provision; as before declared.

David has said what he had to say to Solomon. But he had something more to say to the congregation before he parted with them. I. He pressed them to contribute, according to their ability, towards the building and furnishing of the temple (Ch1 29:1-5). II. They made their presents accordingly with great generosity (Ch1 29:6-9). III. David offered up solemn prayers and praises to God upon that occasion (Ch1 29:10-20), with sacrifices (Ch1 29:21, Ch1 29:22). IV. Solomon was hereupon enthroned, with great joy and magnificence (Ch1 29:23-25). V. David, soon after this finished his course (Ch1 29:26-30). And it is hard to say which shines brighter here, the setting sun or the rising sun.

29:18-19 David did not ask God to grant power, victory, or riches, or for the establishment of Solomon’s kingdom. Instead he asked God to make the people of Israel, and Solomon in particular, always want to obey the Lord. Gaining this kind of heart attitude is a gift from the Lord; success and prosperity are secondary.
