The climax of the foreign oracles is that against Babylon (l.-li. 58). This prophecy is written with great vigour and intensity and characterized by a tone of triumphant scorn. A nation from the north, l. 3, explicitly designated as the Medes, li. 11, is to assail Babylon and reduce her to a desolation. Jehovah's people are urged to leave the doomed city; with sins forgiven they will be led back by Jehovah to their own land, and the poet contemplates with glowing satisfaction the day when Babylon the destroyer will be herself destroyed. This oracle purports to be a message which Jeremiah sent with an officer Seraiah, who accompanied King Zedekiah to Babylon (li. 59). There is no probability, however, that the oracle was written by Jeremiah. Doubtless the prophet foretold the destruction of Babylon, xxv. 10, but his attitude to that great power in this oracle is altogether different from what we know it to have been, judging by other authentic oracles of this period (xxvii.-xxix.). There he counsels patience--it is the false prophets who hope for a speedy deliverance--here there is an eager expectancy which amounts to impatience. But the contents of the oracle show that it cannot belong to the year to which it is assigned. The temple is already destroyed, l. 28, li. 11, so that the exile is presupposed, and indeed the Medes are definitely named as the executors of vengeance upon Babylon. All this carries us down to the conquests of Cyrus and the close of the exile, indeed to the time of Isaiah xl.-lv. The oracle bears a striking resemblance both in spirit and expression to Isaiah xiii., and might well come from the same time (about 540). It may, however, be later. Not only is it diffuse in expression and slipshod in arrangement, but it borrows extensively from other exilic or post-exilic parts of the book of Jeremiah (cf. li. 15-19 with x. 12-16, l. 44-46 with xlix. 19-21), late exilic parts of Isaiah (cf. Jer. l. 39ff, with Isa. xiii. 19-22), and from Ezekiel (cf. Jer. li. 25 with Ezek. xxxv. 3). Besides, the author appears to have no clear conception of the actual situation, as he seems to regard Israel and Judah as living side by side in Babylon, l. 4, 33. In all probability the oracle against Babylon is a post-exilic production inspired by the yearning to see the ancient oppressors not only humbled, but destroyed. The oracle just discussed is supposed to be an expansion of the message given by Jeremiah, in writing, to Seraiah, li. 60a, when he went with the king to Babylon. But though this narrative, li. 59-64, possibly rests on a basis of fact, it cannot have come, in its present form, from Jeremiah, for it presupposes the preceding oracle against Babylon, which has just been shown not to be authentic.
