David
Psalm 19:2ASV·superscription

Day unto day uttereth speech, And night unto night showeth knowledge.

C.H. Spurgeon Reformed Baptist

The heavens are a fountain perpetually flowing with God's praise, pouring forth without ceasing. Those witnesses above cannot be silenced; they preach His knowledge unawed by the judgment of men. Even our changing circumstances, day's labor and night's rest, joy and sorrow, should teach us to extol Him, to work for God by day and prepare for eternity by night.

Keil & Delitzsch Lutheran

The heavens declare God's glory not as conscious beings, Scripture knows nothing of such Aristotelian notions, but as an unvoiced witness, a reflection of God's own majesty given back to Him in acknowledgment. The testimony pours forth from day to day like an inexhaustible spring, an uninterrupted line of transmission that carries forward perpetually.

John Calvin Reformed

David sets before us two mirrors of God's glory: first the heavens themselves with their exquisite order, then the Law in which God made Himself known to His chosen people. From this he moves to praise the Law at length before closing with prayer.
