Concerning the works of men, by the word of your lips I have kept myself from the paths of the destroyer.
All Commentaries on Psalms 17:4 Go To Psalms 17
Augustine of Hippo
AD 430
4. "That My mouth may not speak the works of men" (ver. 4). That nothing may proceed out of My mouth, but what relates to Thy glory and praise; not to the works of men, which they do beside Thy will. "Because of the words of Thy lips." Because of the words of Thy peace, or of Thy prophets. "I have kept hard ways." I have kept the toilsome ways of human mortality and suffering.
