This is a historical introduction to this book that gives a name and specific date with a reference to a book, not merely a scroll. The author is Baruch, the same Baruch that was mentioned in the Book of Jeremiah, chapters 32, 36, 43, and 45. This Baruch was a scribe, friend, and follower of Jeremiah. He was clearly identified with a long genealogy. His father was Neriah. His brother Seraiah worked with King Zedekiah. He traced his family back to Hilkiah. Mahseiah, his grandfather was mentioned in Jeremiah also. There were many people with the name of Zedekiah, including the king so that it is hard to pinpoint one. Hasadiah was another common name, while over 30 biblical people have the name Hilkiah. Baruch was in Babylon. However, the last time he was mentioned in Jeremiah, he was with Jeremiah in Egypt. Perhaps, he may have left Jeremiah there. This book is placed 5 years after the fall of Jerusalem and the burning of Jerusalem, around 582 BCE on the 7th day of the month that Jerusalem was destroyed.
Now we are back at the 4th year of the Judean reign of King Zedekiah, about 594 BCE, years before the Babylonian captivity. Jeremiah told Seraiah, the quartermaster or bearer of gifts of the king to go with King Zedekiah to Babylon. Jeremiah’s secretary Baruch and Seraiah had the same father, Neriah, and grandfather, Mahseiah, so that they were brothers.
Jeremiah gave the deed to Baruch, a disciple and friend of Jeremiah. Baruch also was his secretary or scribe who may have written down most of the oracles of Jeremiah. He has been considered the writer of the Book of Baruch, one of the lesser prophets. Baruch was the son of Neriah, whose father was Mahseiah. Somehow he had some relationship with the reigning King Zedekiah of Judah. Watching Jeremiah hand over the deed was his cousin Hanamel, the witnesses who had signed the deed, and all those other people of Judah who were sitting near the royal prison, where Jeremiah was being held.
