Jesaja 40:6

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 penu…

40:6-8 All humanity is mortal and fleeting. By contrast, God persists in his plans and succeeds. Time does not limit him from carrying out his will (see 14:24). 40:6 Shout: So that all can hear. • People are not worthy of the revelation of God’s glory because they are mortal.
