Adam Clarke, on Neh 6:17

“Moreover in those days many letters were sent by the principal men of the Jews to Tobias, and from Tobias there came letters to them.”

“The nobles of Judah sent many letters - The circumstances marked in this and the following verses show still more clearly the difficulties which Nehemiah had to encounter; he had enemies without and false friends within. A treacherous correspondence was carried on between the nobles of Judah and the Ammonites; and had almost any other man been at the head of the Jewish affairs, Jerusalem had never been re-established.”
