Who is this
Jonathan was a scribe in Jerusalem during the time of King Zedekiah of Judah. His house was used as a prison where the prophet Jeremiah was confined (Jeremiah 37:15). Jeremiah appealed to King Zedekiah not to send him back to Jonathan's house, fearing he would die there (Jeremiah 37:20). Later, Jeremiah told the king's officials that he had only petitioned the king not to send him back to Jonathan's house to die when they questioned him (Jeremiah 38:26). Jonathan's role as a scribe and the use of his house as a prison suggest he was a person of some importance in Jerusalem just prior to the Babylonian conquest in 586 BC.
