The statutes of the LORD are right, rejoicing the heart; The commandment of the LORD is pure, enlightening the eyes; The fear of the LORD is clean, enduring forever; The judgments of the LORD are true and righteous altogether.
This is perhaps the most concise statement in all of scripture of the majesty, wonder, and benefit of the precious word of God. David finds different words to describe it: the law, the testimony, the statutes, commandments, and judgments of the Lord. He employs the personal name of God in each phrase, I AM WHO I AM, six times, so there is no doubt about the divine Source of the Word.
Like six massive foundation stones describing the enduring quality and divine nature of God's word, David gives each one a specific adjective, along with a descriptive phrase of each one’s majesty. Muse on each of the six statements and you come to the unavoidable conclusion that there is absolutely no writing on earth, and in fact no other created thing on earth, which can come close to its power and transcendent splendor. It is simply breathtaking.
Nothing else on earth is so perfect, sure, right, pure, clean, or true. Nothing else is able to convert the soul, make the simple wise, rejoice the heart, enlighten the eyes, endure forever, or be righteous altogether.
David ends this section of the psalm with the powerful summary statement about the words of Scripture:
"More to be desired are they than gold, Yea, than much fine gold; Sweeter also than honey and the honeycomb; Moreover by them Your servant is warned, And in keeping them there is great reward" (Psalm 19:10-11).
