But in order to understand the Book of Isaiah, in order to understand Isaiah himself in some of the largest of his activities and hopes, we must traverse this thicket. It would be tedious and unprofitable to search every corner of it. We propose, therefore, to give a list of the various oracles, with their dates and titles, for the guidance of Bible-readers, then to take three representative texts and gather the meaning of all the oracles round them.
First, however, two of the prophecies must be put aside. The twenty-second chapter does not refer to a foreign State, but to Jerusalem itself; and the large prophecy which opens the series (chaps. xiii.-xiv. 23) deals with the overthrow of Babylon in circumstances that did not arise till long after Isaiah's time, and so falls to be considered by us along with similar prophecies at the close of this volume. (See Book V.)
All the rest of these chapters—xiv.-xxi. and xxiii.—refer to Isaiah's own day. They were delivered by the prophet at various times throughout his career; but the most of them evidently date from immediately after the year 705, when, on the death of Sargon, there was a general rebellion of the Assyrian vassals.
1. xiv. 24-27. Oath Of Jehovah that the Assyrian shall be broken. Probable date, towards 701.
2. xiv. 28-32. Oracle For Philistia. Warning to Philistia not to rejoice because one Assyrian king is dead, for a worse one shall arise: Out of the serpent's root shall come forth a basilisk. Philistia shall be melted away, but Zion shall stand. The inscription to this oracle (ver. 28) is not genuine. The oracle plainly speaks of the death and accession of Assyrian, not Judæan, kings. It may be ascribed to 705, the date of the death of Sargon and accession of Sennacherib. But some hold that it refers to the previous change on the Assyrian throne—the death of Salmanassar and the accession of Sargon.
3. xv.-xvi. 12. Oracle for Moab. A long prophecy against Moab. This oracle, whether originally by himself at an earlier period of his life, or more probably by an older prophet, Isaiah adopts and ratifies, and intimates its immediate fulfilment, in xvi. 13, 14. This is the word which Jehovah spake concerning Moab long ago. But now Jehovah hath spoken, saying, Within three years, as the years of an hireling, and the glory of Moab shall be brought into contempt with all the great multitude, and the remnant shall be very small and of no account. The dates both of the original publication of this prophecy and of its reissue with the appendix are quite uncertain. The latter may fall about 711, when Moab was threatened by Sargon for complicity in the Ashdod conspiracy (p. 198), or in 704, when, with other States, Moab came under the cloud of Sennacherib's invasion. The main prophecy is remarkable for its vivid picture of the disaster that has overtaken Moab and for the sympathy with her which the Jewish prophet expresses; for the mention of a remnant of Moab; for the exhortation to her to send tribute in her adversity to the mount of the daughter of Zion (xvi. 1); for an appeal to Zion to shelter the outcasts of Moab and to take up her cause: Bring counsel, make a decision, make thy shadow as the night in the midst of the noonday; hide the outcasts, bewray not the wanderer; for a statement of the Messiah similar to those in chaps. ix. and xi.; and for the offer to the oppressed Moabites of the security of Judah in Messianic times (vv. 4, 5). But there is one great obstacle to this prospect of Moab lying down in the shadow of Judah—Moab's arrogance. We have heard of the pride of Moab, that he is very proud (ver. 6, cf. Jer. xlviii. 29, 42; Zeph. ii. 10), which pride shall not only keep this country in ruin, but prevent the Moabites prevailing in prayer at their own sanctuary (ver. 12)—a very remarkable admission about the worship of another god than Jehovah.
4. xvii. 1-11. Oracle for Damascus. One of the earliest and most crisp of Isaiah's prophecies. Of the time of Syria's and Ephraim's league against Judah, somewhere between 736 and 732.
5. xvii. 12-14. Untitled. The crash of the peoples upon Jerusalem and their dispersion. This magnificent piece of sound, which we analyse below, is usually understood of Sennacherib's rush upon Jerusalem. Verse 14 is an accurate summary of the sudden break-up and "retreat from Moscow" of his army. The Assyrian hosts are described as nations, as they are elsewhere more than once by Isaiah (xxii. 6, xxix. 7). But in all this there is no final reason for referring the oracle to Sennacherib's invasion, and it may just as well be interpreted of Isaiah's confidence of the defeat of Syria and Ephraim (734-723). Its proximity to the oracle against Damascus would then be very natural, and it would stand as a parallel prophecy to viii. 9: Make an uproar, O ye peoples, and ye shall be broken in pieces; and give ear, all ye of the distances of the earth: gird yourselves, and ye shall be broken in pieces; gird yourselves, and ye shall be broken in pieces—a prophecy which we know belongs to the period of the Syro-Ephraimitic league.
6. xviii. Untitled. An address to Ethiopia, land of a rustling of wings, land of many sails, whose messengers dart to and fro upon the rivers in their skiffs of reed. The prophet tells Ethiopia, cast into excitement by the news of the Assyrian advance, how Jehovah is resting quietly till the Assyrian be ripe for destruction. When the Ethiopians shall see His sudden miracle, they shall send their tribute to Jehovah, to the place of the name of Jehovah of hosts, Mount Zion. It is difficult to know to which southward march of Assyria to ascribe this prophecy—Sargon's or Sennacherib's? For at the time of both of these an Ethiopian ruled Egypt.
7. xix. Oracle for Egypt. The first fifteen verses describe judgement as ready to fall on the land of the Pharaohs. The last ten speak of the religious results to Egypt of that judgement, and they form the most universal and "missionary" of all Isaiah's prophecies. Although doubts have been expressed of the Isaian authorship of the second half of this chapter on the score of its universalism, as well as of its literary style, which is judged to be "a pale reflection" of Isaiah's own, there is no final reason for declining the credit of it to Isaiah, while there are insuperable difficulties against relegating it to the late date which is sometimes demanded for it. On the date and authenticity of this prophecy, which are of great importance for the question of Isaiah's "missionary" opinions, see Cheyne's introduction to the chapter and Robertson Smith's notes in The Prophets of Israel (p. 433). The latter puts it in 703, during Sennacherib's advance upon the south. The former suggests that the second half may have been written by the prophet much later than the first, and justly says, "We can hardly imagine a more 'swan-like end' for the dying prophet."
