Scribe and Companion of Jeremiah
Baruch's defining role in Scripture is that of Jeremiah's scribe. When the prophet was barred from the Temple, he summoned Baruch and dictated to him the words the Lord had spoken; Baruch wrote them on a scroll and read them to the assembled people. Twice the prophecies were recorded in this way, and the bond between prophet and secretary was close enough that the tradition calls Baruch Jeremiah's inseparable companion, disciple, and friend.
Together the two men lamented the catastrophe that overtook Judah. They witnessed the siege and destruction of Jerusalem by the Babylonians under Nebuchadnezzar, and Baruch's faithfulness amid the ruin of his nation is the heart of his commemoration. Beyond his historical role, the tradition ascribes to him prophecy foretelling the return of the Jews from the Babylonian captivity, the desolation of Babylon, and, by Christian reading, the Incarnation of Christ.
