³ tn The term יְסוֹד (yÿsod, “foundation”) refers to the ground-level and below ground-level foundation stones of a city wall (Ps 137:7; Lam 4:11; Mic 1:6).

⁴ sn Edom apparently in some way assisted in the destruction of Jerusalem in 587/6 b.c. (Ps 137:7; Lam 5:21, 23; Joel 3:19; Obadiah).

¹ sn The date of the book of Obadiah is very difficult to determine. Since there is no direct indication of chronological setting clearly suggested by the book itself, and since the historical identity of the author is uncertain as well, a possible date for the book can be arrived at only on the basis of internal evidence. When did the hostile actions of Edom against Judah that are described in this book take place? Many nineteenth-century scholars linked the events of the book to a historical note found in 2 Kgs 8:20 (cf. 2 Chr 21:16-17): “In [Jehoram’s] days Edom rebelled from under the hand of Judah and established a king over themselves.” If this is the backdrop against which Obadiah should be read, it would suggest a ninth-century b.c. date for the book, since Jehoram reigned ca. 852-841 b.c. But the evidence presented for this view is not entirely convincing, and most contemporary Old Testament scholars reject a ninth-century scenario. A more popular view, held by many biblical scholars from Luther to the present, understands the historical situation presupposed in the book to be the Babylonian invasion of Judah in the sixth century (cf. Ps 137:7; Lam 4:18-22; Ezek 25:12-14; 35:1-15). Understood in this way, Obadiah would be describing a situation in which the Edomites assisted in the Babylonian sack of Jerusalem. Although it must be admitted that a sixth-century setting for the book of Obadiah cannot be proven, the details of the book fit reasonably well into such a context. Other views on the dating of the book, such as an eighth-century date in the time of Ahaz (ca. 732-716 b.c.) or a fifth-century date in the postexilic period, are less convincing. Parallels between the book of Obadiah and Jer 49:1-22 clearly suggest some kind of literary dependence, but it is not entirely clear whether Jeremiah drew on Obadiah or whether Obadiah drew upon Jeremiah, In any case, the close relationship between Obadiah and Jer 49 might suggest the sixth-century setting.
