Besides these, the collection contains oracles against Moab (Isa. 15 f.), Nubia (c. 18), Egypt (c. 19), another vision of the fall of Babylon before the armies of Elam and Media (xxi. 1-10), but in a different spirit from cc. 13-14, the Arabs (xxi. 11 f., 13-17), Tyre (c. 23), and one with the mysterious (editorial) title "Burden of the Valley of Vision" (xxii. 1-14). The last-named, in the form of a vision, depicts a crisis in the history of Jerusalem, and condemns the frivolous behaviour of its inhabitants on the eve of a siege or, as some think, during the respite given by a temporary raising of a siege. It was probably uttered by Isaiah at an early stage in Hezekiah's revolt against Sennacherib (704 or 703 B.C.), before the actual appearance of the Assyrian army. The oracle against Tyre (Isa. xxiii. 1-14--what follows is a later supplement) seems more appropriate to the thirteen years' siege by Nebuchadnezzar than to the operations of Shalmanezer or of Sennacherib in Isaiah's days. Thus Isa. 13-23, like cc. 1-12, contains prophecies of Isaiah from both the earliest and the latest period of his activity, intermingled with others having a totally different historical horizon and dating from a much later time, and to both additions have been made by editors or scribes. A very interesting example of the latter phenomenon is Isa. xix. 18 ff. The passage is, in all probability, from the time of the Greek kingdoms of Egypt and Syria, the name of the city in the Greek Bible, "City of Righteousness," referring to Leontopolis, where a Jewish temple was erected about 170 B.C., with high priests of the legitimate line exiled from Jerusalem. "City of Destruction" (_heres_) in the Hebrew text is a hostile perversion, possibly by way of another reading "City of the Sun" (_heres_). Each of the three large prophetic books has such a group of oracles about gentile nations, Isa. 13-23; Jer. 46-51; Ezek. 25-32. They are in part levelled at the immediate neighbours of Judah, in part against the great powers, Babylon and Egypt. Many of them are in such general terms--or, if they refer to specific events and situations, our knowledge of the history is so incomplete--that it is peculiarly difficult to fix their age. It was also a kind of prophecy which peculiarly invited imitation. Under the foreign yoke the Jews wore for so many centuries, it must often have been a relief of soul to repeat what God was going to do to the heathen; the spirit of the author of Jonah was not for everybody. Moreover, if there is any place in the Old Testament where it would be easier than another for oracles of the "false prophets" to slip in and be preserved, it is in these collections; about the doom of the enemies of Israel they were as orthodox and as emphatic as the best. It is not strange, therefore, that there should be more than usual uncertainty about the origin of these anathemas on the gentiles.
