All this, said David, the LORD made me understand in writing {k} by his hand upon me, even all the works of this pattern.

(k) For all this was left in writing in the book of the Law, Ex 25:40, which the king was bound to put in execution, De 17:19.

Wesley's Notes

28:19 In writing - God revealed this to some man of God, who put it into writing, and by him to David. Or, God did, as it were, by his own hand, (where - with he wrote the Ten Commandments) write these things upon the table of his mind.

Matthew Henry's Concise Commentary

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.
