Isa 51:7-8
Upon this magnificent promise of the final triumph of the counsel of God, an exhortation is founded to the persecuted church, not to be afraid of men. “Hearken unto me, ye that know about righteousness, thou people with my law in the heart; fear ye not the reproach of mortals, and be ye not alarmed at their revilings. For the moth will devour them like a garment, and the worm devour them like woollen cloth; and my righteousness will stand for ever, and my salvation to distant generations.” The idea of the “servant of Jehovah,” in its middle sense, viz., as denoting the true Israel, is most clearly set forth in the address here. They that pursue after righteousness, and seek Jehovah (Isa 51:1), that is to say, the servants of Jehovah (Isa 65:8-9), are embraced in the unity of a “people,” as in Isa 65:10 (cf., Isa 10:24), i.e., of the true people of God in the people of His choice, and therefore of the kernel in the heart of the whole mass - an integral intermediate link in the organism of the general idea, which Hävernick and, to a certain extent, Hofmann eliminate from it, but not without thereby destroying the typical mirror in which the prophet beholds the passion of the One. The words are addressed to those who know from their own experience what righteousness is as a gift of grace, and as conduct in harmony with the plan of salvation, i.e., to the nation, which bears in its heart the law of God as the standard and impulse of its life, the church which not only has it as a letter outside itself, but as a vital power within (cf., Psa 40:9). None of these need to be afraid of men. Their despisers and blasphemers are men ('ĕnōsh; cf., Isa 51:12, Psa 9:20; Psa 10:18), whose pretended omnipotence, exaltation, and indestructibility, are an unnatural self-convicted lie. The double figure in Isa 51:8, which forms a play upon words that cannot well be reproduced, affirms that the smallest exertion of strength is quite sufficient to annihilate their sham greatness and sham power; and that long before they are actually destroyed, they carry the constantly increasing germ of it within themselves. The sâs, says a Jewish proverb, is brother to the ‛âsh. The latter (from ‛âshēsh, collabi, Arab. ‛aththa, trans. corrodere) signifies a moth; the former (like the Arabic sūs, sūse, Gr. σής) a moth, and also a weevil, curculio. The relative terms in Greek are σής (Armen. tzetz) and κίς. But whilst the persecutors of the church succumb to these powers of destruction, the righteousness and salvation of God, which are even now the confidence and hope of His church, and the full and manifest realization of which it will hereafter enjoy, stand for ever, and from “generation to generation,” ledōr dōrı̄m, i.e., to an age which embraces endless ages within itself.
