Ezra 4:8, 9, 17

Rehum the commanding officer and Shimshai the secretary wrote a letter against Jerusalem to Artaxerxes the king as follows

Rehum the commanding officer and Shimshai the secretary, together with the rest of their associates—the judges, officials and administrators over the people from Persia, Uruk and Babylon, the Elamites of Susa

The king sent this reply: To Rehum the commanding officer, Shimshai the secretary and the rest of their associates living in Samaria and elsewhere in Trans-Euphrates: Greetings.
