George Haydock's Catholic Commentary
Psalms 20:11
Fruit of the womb, or all their possessions. The family of Herod was presently extirpated. (Berthier) --- The works of the wicked must burn. (St. Augustine) --- The severity shewn to the Ammonites was perhaps without example, ver. 10. (Calmet) --- But this will be more fully verified in the judgment of the wicked, whose schemes against Christ and his Church will fail. (Worthington)
