Rehum the commander and Shimshai the scribe wrote a letter against Jerusalem to Artaxerxes the king in this sort—
Rashi on Ezra
Rehum was the secretary Rehum was the secretary and the master of words to compose the epistle.
Rashi on Ezra
and Shimshai was the scribe And Shimshai was the scribe: he is Shimshai the son of Haman. So it is customary to mention the scribe and the secretary together because they need each other; one composes and dictates, and the scribe writes, as it says (I Kings 4:3): “Eliphoreph and Ahiah, the sons of Shisha, scribes, Jehoshaphat, the son of Ahlud, the secretary,” and in another place it says (Isa. 36: 22): “And Eliakim, the son of Hilkiah etc. and Shebna the scribe, and Joah, the son of Asaph the secretary, came.”
Rashi on Ezra
they wrote a letter These two, Rehum and Shimshai, wrote the letter as Mithredath Tabeel had commanded them, and they all were dwellers of the cities of Samaria.
