The fear of the LORD is clean, enduring for ever: the judgments of the LORD are true and righteous altogether.
The fear of the Lord is clean, enduring for ever. "The fear of the Lord" is shown by the parallelism to mean the parts of God's law which inspire reverential fear (as, for instance, those which set forth the awful majesty of God, His justice, and wrath against sin). Compare Deuteronomy 17:18-19; Exodus 20:18; Deuteronomy 5:23-24. The law, in this point of view, is "the fear of the Lord" just as God Himself is called "the fear of Isaac" (Genesis 31:42; Genesis 31:53; Isaiah 8:13). The law is clean - i:e., pure, hallowed; requiring holy separation from all uncleanness (2 Corinthians 7:1); requiring purity and sincerity in the worshippers (John 4:24; 1 Timothy 2:8); admitting of no alloy of hypocrisy or impurity х Tªhowraah (H2889)]. The whole Old Testament law, in its substance and spirit, is enduring for ever. Christ "came not to destroy, but to fulfil" it. The enduring character of the law is the result of its purity.
Judgments of the Lord are true - i:e., the ordinances of the law concerning the relative duties of man and man (Exodus 21:1). These are based on the eternal principles of truth.
