David also commanded all the princes of Israel to help Solomon his son, saying,

Matthew Henry's Concise Commentary

22:17-19 Whatever is done towards rendering the word of God generally known and attended to, is like bringing a stone, or an ingot of gold, towards erecting the temple. This should encourage us when we grieve that we do not see more fruit of our labours; much good may appear after our death, which we never thought of. Let us not then be weary of well doing. The work is in the hands of the Prince of peace. As he, the Author and Finisher of the work, is pleased to employ us as his instruments, let us arise and be doing, encouraging and helping one another; working by his rule, after his example, in dependence on his grace, assured that he will be with us, and that our labour shall not be in vain in the Lord.

Matthew Henry's Whole Bible Commentary

Verses 17-19

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, v. 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 (v. 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.
