Cursed be he, &c.— "Cursed is he who doth not execute with fidelity and the greatest exactness the orders of the Lord; cursed will ye be, O Chaldeans, if you spare Moab, if you treat her not with the utmost severity, since God hath appointed her to destruction, and you are only the executors of his just vengeance." Calmet.
