Charles H. Spurgeon on Psalms 119:85

Which are not after thy law. After God's law they could not be while they were doing such things. Perhaps he refers to the deed more than to the men "The proud have digged pits for me, which is not after thy law" which is against thy law; and they would seem to do it because it is against thy law delighting in wickedness as they do. Such men would seem to imbibe the foul spirit which Milton ascribes to the fallen archangel: "Evil, be thou my good." Obviously, however, the words contain this sentiment, The proud have sought to overthrow me, because they are not obedient to thy law. Hereupon he sets their conduct in the light of God's holy commandments, that the comparison may be made: "All thy commandments are faithful: they persecute me wrongfully." Whatever the Lord did was done in truth; these men acted against his servant without cause, and in so doing they also acted in defiance of his known will. John Stephen.
