George Haydock's Catholic Commentary
Psalms 17:48
Avengest, or "grantest me revenges," (Haydock) and the victory; inflicting a just punishment on the wicked. David was too well informed to delight in sentiments of revenge, 3 Kings iii. 11. Jesus Christ takes vengeance on his enemies, but this id done without passion. The love of justice is his only motive. David approves of this conduct. (Calmet) --- Enraged enemies. Vulgate iracundis. (Haydock) --- Septuagint have thus explained aph, "wrath;" others join it with the following verse, "But (Calmet) or yea," (Haydock) etiam. The former version is, however, very accurate. (Berthier)
