The prophet’s letter reinforces his previous prophecies that God has granted Babylon hegemony, that the duration of Babylonian sovereignty has decades to run (cf. 25:12), and that only then will there be restoration (cf. 24:6–7). What is new in chapter 29 is the instruction to settle down in Babylon and to pray for the city. The exiles are to “seek the peace and prosperity of the city to which I have carried you into exile. Pray to the LORD for it, because if it prospers, you too will prosper” (29:7).
