George Haydock's Catholic Commentary
Psalms 36:28
Saints. Hebrew, "merciful ones." He will free them from captivity. (Calmet) --- Punished. This sentence seems to be improperly omitted in Hebrew, which otherwise neglects the letter a, as the Chaldean, Syriac, and St. Jerome do as well as a few copies of the Septuagint. The Roman edition with the Arabic and Ethiopic, reads Greek: amomoi ekdikethesontai, "the innocent shall be avenged," (Calmet) or "punished;" which is inaccurately put for Greek: anomoi ekdiochthesontai, the wicked shall be punished, or "expelled;" (Berthier) though Grabe prefers the former verb. (Haydock) --- St. Cyril acknowledges both readings. (Calmet)
