I Chronicles 22:17

Is not the Lord your God with you?.... Blessing them with wealth and riches: and hath he not given you rest on every side? from all enemies within and without; so that they had peace and quietness, and leisure to attend the service he recommended to them: for he hath given the inhabitants of the land into my hand; meaning the rest of the Canaanites, who before were unsubdued, as even the Jebusites in Jerusalem: and the land is subdued before the Lord, and before his people; and the extent of it carried to its utmost bounds, as God had promised.

David here engages the princes of Israel to assist Solomon in the great work he had to do, and every one to lend him a hand towards the carrying of it on. Those that are in the throne cannot do the good they would, unless those about the throne set in with them. David would therefore have the princes to advise Solomon and quicken him, and make the work as easy to him as they could, by promoting it every one in his place. 1. He shows them what obligations they lay under to be zealous in this matter, in gratitude to God for the great things he had done for them. He had given them victory, and rest, and a good land for an inheritance, Ch1 22:18. The more God has done for us the more we should study to do for him. 2. He presses that upon them which should make them zealous in it (Ch1 22:19): "Set your heart and soul to seek God, place your happiness in his favour, and keep your eye upon his glory. Seek him as your chief good and highest end, and this with your heart and soul. Make religion your choice and business; and then you will grudge no pains nor cost to promote the building of his sanctuary." Let but the heart be sincerely engaged for God, and the head and hand, the estate and interest, and all will be cheerfully employed for him.
