Baruch ben Neriah (בָּרוּךְ בֶּן־נֵרִיָּה Bārūḵ ben Nērīyyā; c. 6th century BC) was the scribe, disciple, secretary, and devoted friend of the Biblical prophet Jeremiah. He is traditionally credited with authoring the Book of Baruch.
According to Josephus, Baruch was a Jewish aristocrat, a son of Neriah and brother of Seraiah ben Neriah, chamberlain of King Zedekiah of Judah.
Baruch became the scribe of the prophet Jeremiah and wrote down the first and second editions of his prophecies as they were dictated to him. Baruch remained true to the teachings and ideals of the great prophet, although like his master he was at times almost overwhelmed with despondency. While Jeremiah was in hiding to avoid the wrath of King Jehoakim, he commanded Baruch to read his prophecies of warning to the people gathered in the Temple in Jerusalem on a day of fasting. The task was both difficult and dangerous, but Baruch performed it without flinching and it was probably on this occasion that the prophet gave him the personal message (Jeremiah 45).
Both Baruch and Jeremiah witnessed the Babylonian siege of Jerusalem of 587–586 BC. In the middle of the siege of Jerusalem, Jeremiah purchased an estate in Anathoth on which the Babylonian armies had encamped (as a symbol of faith in the eventual restoration of Jerusalem; Jeremiah 32) and, according to Josephus, Baruch continued to reside with him at Mizpah.
He was carried with Jeremiah to Egypt, where, according to a tradition preserved by Jerome, he soon died. Two other traditions state that he later went, or was carried, to Babylon by Nebuchadnezzar II after the latter's conquest of Egypt.
Baruch's prominence, by reason of his intimate association with Jeremiah, led later generations to exalt his reputation still further. To him were attributed the Book of Baruch and two other Jewish books.
In 1975, a clay bulla purportedly containing Baruch's seal and name appeared on the antiquities market. Its purchaser, a prominent Israeli collector, permitted Israeli archaeologist Nahman Avigad to publish the bulla.
