George Haydock's Catholic Commentary
Psalms 64:13
Wilderness. Or, of such places are were not ploughed. Little hay was collected, as cattle might almost always pasture. --- Hills, covered with vine-trees, &c., Joel iii. 18., and Job xx. 17. (Calmet) --- The most barren will bring forth fruit, and the perfect shall advance in merit. (Worthington)
