John Gill Commentary Proverbs 3:19

"Jehovah by wisdom founded the earth; By understanding he established the heavens." — Proverbs 3:19 (ASV)

The Lord by wisdom has founded the earth He has created all things, and made the world by his Son, the Wisdom of God, (Ephesians 3:9) (Hebrews 1:2) ; not using him as an instrument; but, he being an efficient cause with him, to him, as to the first cause, the creation of all things is ascribed, (John 1:1–3) (Colossians 1:16) ; and particularly the laying the foundation of the earth, (Hebrews 1:10) ; and though this is true of the divine perfection of wisdom, (Jeremiah 10:12) ; yet from the context it appears best to understand it of the essential Wisdom of God, Christ Jesus; the Jerusalem Targum of (Genesis 1:1) ; is, "by wisdom God created", &c. and this serves greatly to set forth the dignity and excellency of Wisdom, or Christ, and so the happiness of that man that finds him; with this the account of him is closed and crowned;

by understanding has he established the heavens : or prepared, adorned, and beautified them, by placing the luminaries in them, and directing their station, motion, and influence; the making of the heavens, with all the host of them, is ascribed to the essential Word or Wisdom of God, (Psalms 33:6) .
