George Haydock's Catholic Commentary
Psalms 118:126
To do. Our best, since so many prove rebellious, (Hebrews iv. 11., and Ecclesiasticus v. 8.; Berthier) or we stand in the utmost need of the Messias, since even the Jews give erroneous explanations of the law. (St. Ambrose) --- Hebrew, &c., "it is time for the Lord to act," by punishing the guilty; or, "to act for the Lord," faciendi Domino, by striving to repair the injuries done to his name and worship. (Calmet)
