Who was Baruch in the Bible

Baruch was the scribe who helped Jeremiah to write and read his divine message to the people.
Then Jeremiah took another scroll and gave it to Baruch the scribe, the son of Neriah, who wrote on it at the dictation of Jeremiah all the words of the scroll that Jehoiakim king of Judah had burned in the fire. And many similar words were added to them. JEREMIAH 36:32 ESV
The story line is familiar enough: Someone has written a scathing article against ongoing evil, and now he is being attacked. Sound like the lead news story from a couple of weeks ago? Actually, it’s the story of Baruch, the personal scribe of the prophet Jeremiah, who demonstrated his faithfulness by willingly risking his life to record and recite Jeremiah’s messages from God.
Baruch may have come from a noble family, since he appears to have been related to a staff officer who was exiled to Babylon along with all the other leading families of Judah (Jeremiah 51:59). Nevertheless, his high position did not deter him from linking his fate to that of Jeremiah, who was often harassed and even imprisoned by Judean leaders for his messages of judgment.

We first hear of Baruch when he helps Jeremiah with the process of purchasing land in his hometown. After that Jeremiah dictated a message of divine judgment for the nation of Judah and instructed Baruch to read it before the people at the temple. Baruch did so, and the message led the king to put out an order for the arrest of Baruch and Jeremiah (Jeremiah 36). The Lord kept them hidden, however, and eventually Baruch accompanied Jeremiah to Egypt along with the other exiles who were fleeing from the wrath of the Babylonians (Jeremiah 43:1–7).
The Bible does not record anything further about Baruch after he accompanied Jeremiah to Egypt, but the early church leader Jerome wrote that some people in his day believed that Baruch died soon after arriving in Egypt. In 1975 a seal of Baruch was believed to have been discovered.
