George Haydock's Catholic Commentary
Psalms 17:46
Faded, ( inveterati sunt) "are grown old." (Haydock) --- The Jews had been long the objects of God's favours: yet they fell away. Thus we often see priests outdone in piety by simple laics. (Berthier) --- David continues in the comparison of a tree which bears no fruit; (Calmet) thus lying, as it were, and frustrating the just expectations of the owner. Subjects do the like, when they revolt; (Isaias xxx. 9.) and thus deserve the title of strange. Protestants, "the strangers shall fade away, and be afraid out of their close places;" (St. Jerome) "shall flow away, and be contracted in their straits;" while I shall be at large, ver. 37. The last verb gachregu, (Haydock) occurs no where else. It may signify "shall be withered," or burnt, from carar. (Calmet)
