The prophet now hears a second voice, and then a third, entering into conversation with it. "Hark, one speaking, Cry! And he answers, What shall I cry? All flesh is grass, and all its beauty as the flower of the field. Grass is withered, flower faded: for the breath of Jehovah has blown upon it. Surely grass is the people; grass withereth, flower fadeth: yet the word of our God will stand for ever." A second voice celebrates the divine word of promise in the face of the approaching fulfilment, and appoints a preacher of its eternal duration. The verb is not ואמר (et dixi, lxx, Vulg.), but ואמר; so that the person asking the question is not the prophet himself, but an ideal person, whom he has before him in visionary objectiveness. The appointed theme of his proclamation is the perishable nature of all flesh ( Isa 40:5 πᾶσα σάρξ, here πᾶσα ἡ σάρξ), and, on the other hand, the imperishable nature of the word of God. Men living in the flesh are universally impotent, perishing, limited; God, on the contrary ( Isa 31:3), is the omnipotent, eternal, all-determining; and like Himself, so is His word, which, regarded as the vehicle and utterance of His willing and thinking, is not something separate from Himself, and therefore is the same as He. Chasdō is the charm or gracefulness of the outward appearance (lxx; Pe1 1:24, δόξα: see Schott on the passage, Jam 1:11, εὐπρέπεια). The comparison instituted with grass and flower recals Isa 37:27 and Job 8:12, and still more Psa 90:5-6, and Job 14:2. Isa 40:7 describes what happens to the grass and flower. The preterites, like the Greek aoristus gnomicus (cf., Isa 26:10), express a fact of experience sustained by innumerable examples: exaruit gramen, emarcuit flos; (Note: נבל has munach here and in Isa 40:8 attached to the penultimate in all correct texts (hence milel, on account of the monosyllable which follows), and mehteg on the tzere to sustain the lengthening.) consequently the כּי which follows is not hypothetical (granting that), but explanatory of the reason, viz., "because rūăch Jehovah hath blown upon it," i.e., the "breath" of God the Creator, which pervades the creation, generating life, sustaining life, and destroying life, and whose most characteristic elementary manifestation is the wind. Every breath of wind is a drawing of the breath of the whole life of nature, the active indwelling principle of whose existence is the rūăch of God. A fresh v. ought to commence now with אכן. The clause העם חציר אכן is genuine, and thoroughly in Isaiah's style, notwithstanding the lxx, which Gesenius and Hitzig follow. עכן is not equivalent to a comparative כן (Ewald, 105, a), but is assuring, as in Isa 45:15; Isa 49:4; Isa 53:4; and hâ‛âm (the people) refers to men generally, as in Isa 42:5. The order of thought is in the form of a triolet. The explanation of the striking simile commences with 'âkhēn (surely); and then in the repetition of the words, "grass withereth, flower fadeth," the men are intended, resemble the grass and the flower. Surely grass is the human race; such grass withereth and such flower fadeth, but the word of our God (Jehovah, the God of His people and of sacred history) yâqūm le‛ōlâm, i.e., it rises up without withering or fading, and endures for ever, fulfilling and verifying itself through all times. This general truth refers, in the preset instance, to the word of promise uttered by the voice in the desert. If the word of God generally has an eternal…
