Isa 2:1
The limits of this address are very obvious. The end of Isa 4:1-6 connects itself with the beginning of chapter 2, so as to form a circle. After various alternations of admonition, reproach, and threatening, the prophet reaches at last the object of the promise with which he started. Chapter 5, on the other hand, commences afresh with a parable. It forms an independent address, although it is included, along with the previous chapters, under the heading in Isa 2:1 : “The word which Isaiah the son of Amoz saw over Judah and Jerusalem.” Chapters 2-5 may have existed under this heading before the whole collection arose. It was then adopted in this form into the general collection, so as to mark the transition from the prologue to the body of the book. The prophet describes what he here says concerning Judah and Jerusalem as “the word which he saw.” When men speak to one another, the words are not seen, but heard. But when God spoke to the prophet, it was in a supersensuous way, and the prophet saw it. The mind indeed has no more eyes than ears; but a mind qualified to perceive what is supersensuous is altogether eye.
The manner in which Isaiah commences this second address is altogether unparalleled. There is no other example of a prophecy beginning with והיה. And it is very easy to discover the reason why. The praet. consecutivum v'hâyâh derives the force of a future from the context alone; whereas the fut. consecutivum vay'hi (with which historical books and sections very generally commence) is shown to be an aorist by its simple form. Moreover, the Vav in the fut. consecut. has almost entirely lost its copulative character; in the praet. consec., on the other hand, it retains it with all the greater force. The prophet therefore commences with “and”; and it is from what follows, not from what goes before, that we learn that hayah is used in a future sense. But this is not the only strange thing. It is also an unparalleled occurrence, for a prophetic address, which runs as this does through all the different phases of the prophetic discourses generally (viz., exhortation, reproof, threatening, and promise), to commence with a promise. We are in a condition, however, to explain the cause of this remarkable phenomenon with certainty, and not merely to resort to conjecture. Isa 2:2-4 do not contain Isaiah’s own words, but the words of another prophet taken out of their connection. We find them again in Mic 4:1-4; and whether Isaiah took them from Micah, or whether both Isaiah and Micah took them from some common source, in either case they were not originally Isaiah's.
Nor was it even intended that they should appear to be his. Isaiah has not fused them into the general flow of his own prophecy, as the prophets usually do with the predictions of their predecessors. He does not reproduce them, but, as we may observe from the abrupt commencement, he quote them. It is true, this hardly seems to tally with the heading, which describes what follows as the word of Jehovah which Isaiah saw. But the discrepancy is only an apparent one. It was the spirit of prophecy, which called to Isaiah’s remembrance a prophetic saying that had already been uttered, and made it the starting-point of the thoughts which followed in Isaiah’s mind. The borrowed promise is not introduced for its own sake, but is simply a self-explaining introduction to the exhortations and threatenings which follow, and through which the prophet works his way to a conclusion of his own, that is closely intertwined with the borrowed commencement.
