George Haydock's Catholic Commentary
Psalms 47:11
Earth. all who hear of the wonders of God, must praise him; and who can be ignorant of what He has done, (Calmet) in the defeat of the enemies of his people, (Haydock) of Sennacherib, Cambyses, &c.? Yet all the earth will be instructed only by the propagation of the Gospel. (Calmet) --- Justice, against thy enemies, (Haydock) though this word may here imply "mercy," in opposition to the judgments, ver. 12. (Calmet) --- These perfections are never at variance. (Worthington)
