Ezra 4:6-7

Now in the reign of Ahasuerus (Xerxes), in the beginning of his reign, the Samaritans wrote [to him] an accusation against the inhabitants of Judah and Jerusalem [who had returned from exile]. Later, in the days of [King] Artaxerxes, Bishlam, Mithredath, Tabeel and the rest of their associates wrote to Artaxerxes king of Persia; and the text of the letter was written in Aramaic and translated from Aramaic.
