The Prophet recites five kinds of caution as continually present in the mind of the happy man: the first, not to walk in the counsel of the ungodly, the second, not to stand in the way of sinners, the third, not to sit in the seat of pestilence, next, to set his will in the Law of the Lord, and lastly, to meditate therein by day and by night. There must, therefore, be a distinction between the ungodly and the sinner, between the sinner and the pestilent; chiefly because here the ungodly has a counsel, the sinner a way, the pestilent a seat, and again, because the question is of walking, not standing, in the counsel of the ungodly; of standing, not walking, in the way of the sinner. Now if we would understand the reason of these facts, we must note the precise difference between the sinner and the undutiful Impius, which is elsewhere in the Homily translated ungodly, is here rendered undutiful, in order to preserve to some extent the sense of undutiful towards parents in which Hilary, with true Roman appreciation of the patria potestas, uses it in this passage., that so it may become clear why to the sinner is assigned a way, and to the undutiful a counsel; next, why the question is of standing in the way, and of walking in the counsel, whereas men are accustomed to connect standing with a counsel, and walking with a way.
