20 Then David said to Solomon his son, "Be strong and courageous and do it. Do not be afraid and do not be dismayed, for the Lord God, even my God, is with you. He will not leave you or forsake you, until all the work for the service of the house of the Lord is finished.
Matthew Henry's Commentary on 1 Chronicles 28:20
Commentary on 1 Chronicles 28:11-21
(Read 1 Chronicles 28:11-21)
The temple must be a sacred thing, and a type of Christ; it must be framed by Divine teaching. Christ is the true temple, the church is the gospel temple, and heaven the everlasting temple; all are framed according to the Divine counsels, and the plan laid in the Divine wisdom, ordained before the world, for God's glory and our good. David gave this pattern to Solomon, that he might go by rule. Materials were provided for the most costly utensils of the temple. Directions were given which way to look for help in this great undertaking. Be not dismayed; God will help thee, and thou must look up to him in the first place. We may be sure that God, who owned our fathers, and carried them through the services of their day, will, in like manner, never leave us, while he has any work to do in us, or by us. Good work is likely to go on, when all concerned are hearty in furthering it. Let us hope in God's mercy; if we seek him, he will be found of us.
