This charge to the princes of Israel, very properly succeeds David's charge to his son. As a dying king he earnestly desired to see every heart engaged in the Lord's work, as certain of the Lord's blessing. So that altogether the whole forms a beautiful representation of the king and court of Israel.
1 Chronicles 22:17-19
17 David also commanded all the princes of Israel to help Solomon his son, saying,
18 Is not the LORD your God with you? and hath he not given you rest on every side? for he hath given the inhabitants of the land into mine hand; and the land is subdued before the LORD, and before his people.
19 Now set your heart and your soul to seek the LORD your God; arise therefore, and build ye the sanctuary of the LORD God, to bring the ark of the covenant of the LORD, and the holy vessels of God, into the house that is to be built to the name of the LORD.
