The fear of the LORD is clean, enduring forever: the judgments of the LORD are true and righteous altogether.
All Commentaries on Psalms 19:9 Go To Psalms 19
Augustine of Hippo
AD 430
10. "The fear of the Lord is chaste, enduring for ever" (ver. 9). "The fear of the Lord;" not that distressing fear under the law, dreading exceedingly the withdrawal of temporal goods, by the love of which the soul commits fornication; but that chaste fear wherewith the Church, the more ardently she loves her Spouse, the more carefully does she take heed of offending Him, and therefore, "perfect love casteth" not "out" this" fear," but it endureth for ever.
