Baruch
Baruch, the son of Neriah, must have lived at the end of the seventh and beginning of the sixth centuries B.C. He acted as scribe to Jeremiah, recording and reading his prophecies of future disasters when Nebuchadnezzar had plundered the Temple. He accompanied Jeremiah into Egypt, and died either there or in Babylon. The book of Baruch found in our Apocrypha can hardly have been by him entirely, as it contains references to events and works of later date. Some of his materials may have been worked up by a Palestinian writer of the third century B.C. The Epistle of Jeremiah which forms the sixth chapter has no connection with Baruch, and was probably composed by a Hellenist of the Maccabean epoch.
