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."
8. xx. UNTITLED. Also upon Egypt, but in narrative and of an earlier date than at least the latter half of xix. Tells how Isaiah walked naked and barefoot in the streets of Jerusalem for a sign against Egypt and against the help Judah hoped to get from her in the years 711-709, when the Tartan, or Assyrian commander-in-chief, came south to subdue Ashdod. See pp. 198-200.
9. xxi. 1-10. ORACLE FOR THE WILDERNESS OF THE SEA, announcing but lamenting the fall of Babylon. Probably 709. See pp. 202, 203.
10. xxi. 11, 12. ORACLE FOR DUMAH. Dumah, or _Silence_--in Ps. xciv. 17, cxv. 17, _the land of the silence of death_, the grave--is probably used as an anagram for Edom and an enigmatic sign to the wise Edomites, in their own fashion, of the kind of silence their land is lying under--the silence of rapid decay. The prophet hears this silence at last broken by a cry. Edom cannot bear the darkness any more. _Unto me one is calling from Seir, Watchman, how much off the night? how much off the night?[52] Said the watchman, Cometh the morning, and also the night: if ye will inquire, inquire, come back again._ What other answer is possible for a land on which the silence of decay seems to have settled down? He may, however, give them an answer later on, if they will come back. Date uncertain, perhaps between 704 and 701.
