John Gill Commentary Psalms 119:104

"Through thy precepts I get understanding: Therefore I hate every false way. NUN." — Psalms 119:104 (ASV)

Through your precepts I get understanding
Of the will of God; of his worship, the nature and manner of it; of his ordinances, their use and importance; and of his doctrines, and the excellency of them;

therefore I hate every false way ;
of worship; all superstition and will worship, the commandments and inventions of men, and every false doctrine; all lies in hypocrisy, for no lie is of the truth; every thing that is contrary to the word of God, and is not according to truth and godliness. The Targum is, ``I hate every lying man.''
