Thomas Aquinas, on Ps 16:4

“That my mouth may not speak the works of men: for the sake of the words of thy lips, I have kept hard ways.”

“Second, he explains by what fire he was examined, when he says, "On account of the words of your lips, I kept to hard ways." Hard ways are adversities; and I endured this on account of the words of your lips, that is, in order to keep your words, or to proclaim your words. Jer. 20: "The word of the Lord became a reproach and a derision to me." Jerome has, "that I might keep to the broad ways." Robbers seek byways to hide; so did David when Saul pursued him. Ps. 17: "He made my feet like those of deer." Spiritually, this is said of Christ, punished among robbers as a malefactor: Jn. 18: "If this man were not a malefactor, we would not have handed him over to you." If you begin the verse at "On account of the works of men, I kept to hard ways," you may say that the hard ways are the works of men. Prov. 4: "I will show you the way of wisdom; I will lead you along the paths of equity, which when you have entered," etc.”
