‏ Isaiah 40:30

Faith is all that is needed to ensure a participation in the strength (עצמה after the form חכמה), which He so richly bestows and so powerfully enhances. “And youths grow faint and weary, and young men suffer a fall. But they who wait for Jehovah gain fresh strength; lift up their wings like eagles; run, and are not weary; go forward, and do not faint.” Even youths, even young men in the early bloom of their morning of life (bachūrı̄m, youths, from בּחר, related to בּכר, בּגר), succumb to the effects of the loss of sustenance or over-exertion (both futures are defective, the first letter being dropped), and any outward obstacle is sufficient to cause them to fall (נכשׁל with inf. abs. kal, which retains what has been stated for contemplation, according to Ges. §131, 3, Anm. 2). In Isa 40:30 the verb stands first, Isa 40:30 being like a concessive clause in relation to Isa 40:31. “Even though this may happen, it is different with those who wait for Jehovah,” i.e., those who believe in Him; for the Old Testament applies to faith a number of synonyms denoting trust, hope, and longing, and thus describes it according to its inmost nature, as fiducia and as hope, directed to the manifestation and completion of that which is hoped for. The Vav cop. introduces the antithesis, as in Isa 40:8. החליף, to cause one to pursue, or new to take the place of the old (Lat. recentare). The expression וגו יעלוּ is supposed by early translators, after the Sept., Targ. Jer., and Saad., to refer to the moulting of the eagle and the growth of the new feathers, which we meet with in Psa 103:5 (cf., Mic 1:16) as a figurative representation of the renewal of youth through grace. But Hitzig correctly observes that העלה is never met with as the causative of the kal used in Isa 5:6, and moreover that it would require נוצה instead of אבר. The proper rendering therefore is, “they cause their wings to rise, or lift their wings high, like the eagles” ('ēbher as in Psa 55:7). Their course of life, which has Jehovah for its object, is as it were possessed of wings. They draw from Him strength upon strength (see Psa 84:8); running does not tire them, nor do they become faint from going ever further and further.

The first address, consisting of three parts (Isa 40:1-11, Isa 40:12-26, Isa 40:27-31), is here brought to a close. Second Prophecy - Isaiah 41

The God of the World’s History and of Prophecy

Jehovah comes forward here, and speaking in the tone in which He already began to speak in Isa 40:25, invites the idolatrous nations to contend with Him, declares the raising up of the conqueror from the east to be His work, and adduces this as the sign that He has been the Author and Guider of the world’s history from the beginning. But what if the question should be asked on the part of the nations, With what right does He do this? The acts of the conqueror prove themselves to be a work of the God who is exalted above the idols, from the fact that they bring destruction to the idolatrous nations, and to the people of Jehovah the long-desired redemption. It is in this that the conclusiveness of the illustration lies. The argument, however, presupposes that Cyrus has already entered upon his victorious course. It is evident at the outset that future events, or events still unfulfilled, would have no force as present proofs. And the words also clearly imply, that the work which Jehovah attributes to Himself, in opposition to the gods of the nations, is already in progress.
