1. 40:1–55:13 Chapters 40–55 are usually designated Second Isaiah (or Deutero-Isaiah) and are believed to have been written by an anonymous prophet toward the end of the Babylonian exile. Isaiah, who is named frequently in chaps. 1–39, does not appear here; the Assyrians, the great threat during the eighth century, hardly appear; the Judeans are in Babylon, having been taken there by the victorious Babylonians; Cyrus, the Persian king, is named; he will defeat Babylon and release the captives. Second Isaiah, who sees this not as a happy circumstance but as part of God’s age-old plan, exhorts the Judeans to resist the temptations of Babylonian religion and stirs up hopes of an imminent return to Judah, where the Lord will again be acknowledged as King (52:7). Because the prophet proclaimed the triumph of Persia over Babylon, his message would have been considered seditious, and it is very likely for this reason that the collection would have circulated anonymously. At some point it was appended to Is 1–39 and consequently was long considered the work of Isaiah of Jerusalem of the eighth century. But the fact that it is addressed to Judean exiles in Babylon indicates a sixth-century date. Nevertheless, this eloquent prophet in many ways works within the tradition of Isaiah and develops themes found in the earlier chapters, such as the holiness of the Lord (cf. note on 1:4) and his lordship of history. Second Isaiah also develops other Old Testament themes, such as the Lord as Israel’s redeemer or deliverer (cf. Ex 3:8; 6:6; 15:13; 18:8).
2. 40:1 The “voices” of vv. 3, 6 are members of the heavenly court addressing the prophet; then v. 1 can be understood as the Lord addressing them. It is also possible to translate, with the Vulgate, “Comfort, give comfort, O my people” (i.e., the exiles are called to comfort Jerusalem). The juxtaposition of “my people” and “your God” recalls the covenant formulary.
3. 40:2 Service: servitude (cf. Jb 7:1) and exile.
