4 Ezra and 2 Baruch share many similarities, although the direction of the influence is hard to determine. Klijn is inclined to see 2 Baruch as dependent on 4 Ezra; he therefore dates the book to the first part of the second century (OTP 1:616-52). Collins argues for a date a bit earlier based on the fall of Jerusalem in the twenty-fifth year of king Jeconiah in the first verse of 2 Baruch. This is not historically accurate, so it is possible the author is referring to the fall of Jerusalem in A.D. 70, twenty-five years in the past (Apocalyptic Imagination, 212-3). The book was written in Palestine and most likely in Hebrew originally. The book is closely related to the rabbinic literature and seems to be exhorting diaspora Jews from the perspective of Palestinian Jews (OTP 1:617).
2 Baruch 1-4 forms an introduction to the book. The author takes on the guise of Baruch son of Neriah, the companion of Jeremiah. He is told by the Lord that all of the things which happened to the northern ten tribes will happen to the south as well. Jerusalem will fall and the people will be punished. Baruch agrees this punishment cannot be resisted, but asks the Lord what will happen after the city is destroyed. Are the promises of God ever to be fulfilled? The Lord’s answer is that a New Jerusalem has been built, but it is in Paradise.
In chapter 5-9 Baruch prepares for the Babylonian invasion. He tells the people what the Lord has told him and they sit in the valley of Kidron and fast until evening. The city is surrounded the next day (ch. 6). Baruch sees four angels at the corners of the city with burning torches. He sees the temple and the Holy of Holies, including the ephod, precious stone and other temple items. These buildings are swallowed up by the earth, then the angels put their torches to the city and destroyed its foundations. Babylon enters the city and plunders it and kill many people.
The word of the Lord comes to Baruch and he is command to tell Jeremiah to go to support the captives in Babylon. Baruch delivers a lengthy lament for the city in chapter 9, striking many themes found in later apocalyptic (“better never to have been born,” verse 6, for example.) He condemns Babylon although it is not as brutal as it might be. He asks how the Lord has borne the destruction of the city (chapter 11-12).
As Baruch weeps for fallen Jerusalem, the Lord will answer his questions through a series of visions
