Ezra 4:4-6

4Then the local residents tried to discourage and frighten the people of Judah to keep them from their work.

5They bribed agents to work against them and to frustrate their plans. This went on during the entire reign of King Cyrus of Persia and lasted until King Darius of Persia took the throne.

6Years later when Xerxes began his reign, the enemies of Judah wrote a letter of accusation against the people of Judah and Jerusalem.
