¹ sn A nation from the north refers to Medo-Persia, which at the time of the conquest of Babylon in 539 b.c. had conquered all the nations to the north, the northwest, and the northeast of Babylon, forming a vast empire to the north and east of Babylon. Contingents of these many nations were included in her army, and reference is made to them in 50:9 and 51:27-28. There is also some irony involved here because the “enemy from the north” referred to so often in Jeremiah (cf. 1:14; 4:6; 6:1) has been identified with Babylon (cf. 25:9). Here in a kind of talionic justice Judah’s nemesis from the north will be attacked and devastated by an enemy from the north.

¹ sn The chronological problems of Ezra 4:6-24 are well known and have been the subject of extensive discussion since ancient times. Both v. 5 and v. 24 describe the reign of Darius I Hystaspes, who ruled Persia ca. 522-486 b.c. and in whose time the rebuilt temple was finished. The material in between is from later times (v. 16 describes the rebuilding of the walls, not the temple), and so appear to be a digression. Even recognizing this, there are still questions, such as why Cambyses (530-522 b.c.) is not mentioned at all, and why events from the time of Xerxes (486-465 b.c.) and Artaxerxes (464-423 b.c.) are included here if the author was discussing opposition to the building of the temple, which was finished in 516 b.c. Theories to explain these difficulties are too numerous to mention here, but have existed since ancient times: Josephus, the first century Jewish historian, rearranged the account to put Cambyses before Xerxes and replacing Artaxerxes with Xerxes (for further discussion of Josephus’ rearrangement see L. L. Grabbe, “Josephus and the Reconstruction of the Judean Restoration” JBL 106 [1987]: 231-46). In brief, it seems best to view the author’s primary concern here as thematic (the theme of opposition to the Jewish resettlement in Jerusalem, including the rebuilding of the temple and restoration of Jerusalem’s walls) rather than purely chronological. In the previous verses the author had shown how the Jews had rejected an offer of assistance from surrounding peoples and how these people in turn harassed them. The inserted account shows how, in light of the unremitting opposition the Jews experienced (even extending down to more recent times), this refusal of help had been fully justified. Some of the documents the author employed show how this opposition continued even after the temple was rebuilt. (The failure to mention Cambyses may simply mean the author had no documents available from that period.) For detailed discussion of the difficulties presented by the passage and the various theories advanced to explain them, see H. G. M. Williamson, Ezra, Nehemiah (WBC), 56-60.
