So let thine enemies perish, O Lord That is, so suddenly, so surely, so effectually and irrecoverably; an elegant apostrophe of the prophetess this, in turning and addressing her speech to God; that as her speech began with him, so it might likewise conclude with him. And with what gracefulness, and, at the same time, with what grandeur and sublimity does she change the subject! How was it possible for her to conclude her song in a finer manner than by this sudden, but, at the same time, earnest wish that all the enemies of Jehovah might perish as Sisera had done. And that all that love him might, like the rising sun, proceed from strength to strength, till they should arrive at the highest pitch of glory. Deborah was a prophetess, and this prayer may be considered as a two-fold prediction, importing both that, in due time, all God's enemies shall perish; and that those who love him in sincerity, and persevere in so doing, shall shine for ever as the sun in the kingdom of their Father.
