A detailed discussion of the question would be out of place here,[243] but we may notice a few passages which illustrate the arguments for an exilic date. We learn from Jeremiah xxvii.-xxix. that, in the fourth year of Zedekiah,[244] the prophet was denouncing as false teachers those who predicted that the Jewish captives in Babylon would speedily return to their native land. He himself asserted that judgment would not be inflicted upon Babylon for seventy years, and exhorted the exiles to build houses and marry, and plant gardens, and to pray for the peace of Babylon.[245] We can hardly imagine that, in the same breath almost, he called upon these exiles to flee from the city of their captivity, and summoned the neighbouring nations to execute Jehovah's judgment against the oppressors of His people. And yet we read:-- "There shall come the Israelites, they and the Jews together: They shall weep continually, as they go to seek Jehovah their God; They shall ask their way to Zion, with their faces hitherward"[246] (l. 4, 5). * * * * * "Remove from the midst of Babylon, and be ye as he-goats before the flock" (l. 8). These verses imply that the Jews were already in Babylon, and throughout the author assumes the circumstances of the Exile. "The vengeance of the Temple," _i.e._ vengeance for the destruction of the Temple at the final capture of Jerusalem, is twice threatened.[247] The ruin of Babylon is described as imminent:-- "Set up a standard on the earth, Blow the trumpet among the nations, Prepare the nations against her." If these words were written by Jeremiah in the fourth year of Zedekiah, he certainly was not practising his own precept to pray for the peace of Babylon. Various theories have been advanced to meet the difficulties which are raised by the ascription of this prophecy to Jeremiah. It may have been expanded from an authentic original. Or again, li. 59-64 may not really refer to l. 1-li. 58; the two sections may once have existed separately, and may owe their connection to an editor, who met with l. 1-li. 58 as an anonymous document, and thought he recognised in it the "book" referred to in li. 59-64. Or again, l. 1-li. 58 may be a hypothetical reconstruction of a lost prophecy of Jeremiah; li. 59-64 mentioned such a prophecy and none was extant, and some student and disciple of Jeremiah's school utilised the material and ideas of extant writings to supply the gap. In any case, it must have been edited more than once, and each time with modifications. Some support might be obtained for any one of these theories from the fact that l. 1-li. 58 is _primâ facie_ partly a cento of passages from the rest of the book and from the Book of Isaiah.[248]
