Through your precepts I get understanding: therefore I hate every false way.
All Commentaries on Psalms 119:104 Go To Psalms 119
Augustine of Hippo
104. But what mean the words, "Through Thy commandments I get understanding"? (ver. 104). For the expressions, I have understood Thy commandments: and, "I get understanding through Thy commandments;" are different. Something else then he signifieth that he hath understood from the commandments of God: that is, as far as I can see, he saith, that by obeying God's commandments he hath arrived at the comprehension of those things which he had longed to know. ...These then are the words of the spiritual members of Christ, "Through Thy commandments I get understanding." For the body of Christ rightly saith these words in those, to whom, while they keep the commandments, a richer knowledge of wisdom is given on account of this very keeping of the commandments. "Therefore," he addeth, "I hate all evil ways." For it is needful that the love of righteousness should hate all iniquity: that love, which is so much the stronger, in proportion as the sweetness of a higher wisdom doth inspire it, a wisdom given unto him who obeyeth God, and getteth understanding from His commandments.
