Chapter 45: The Life of Baruch shall be preserved
Baruch (who had written/read Jeremiah’s prophecies in the temple in Jeremiah 36) is in anguish regarding the destruction of Judah, but is assured that the Lord will build what he has broken down and that his life shall be preserved.
Chapter 46: Conquest of Egypt and Babylon
The prophet sees the preparation of Pharaoh Necho for the battle of Carchemish. In their confidence of victory, the Egyptians are like a river overflowing its banks. However, they will be defeated as the Lord decreed by the river Euphrates. The Egyptians will be overthrown by Nebuchadnezzar after his siege of Tyre. The Jews will be eventually returned to divine favour as Jacob returns to his own land.
