re.chum is the personal name used for the official who writes, receives, and acts on royal correspondence in Ezra.

The name identifies the same official throughout the Ezra episode: he is named with Shimshai in writing to the king, receiving the king’s message, and acting after the letter is read.

   All four occurrences are tagged as a proper noun and name the same figure alongside Shimshai. In Ezra 4:8 the APB renders Rehum and Shimshai as writers of a letter to Artaxerxes; in Ezra 4:17 the king’s message is sent to them, and in Ezra 4:23 they act after the letter is read. Ezra 4:9 again places Rehum with Shimshai and their associates.

In the Anselm Project Bible: The APB consistently presents the term as “Rehum,” naming him with Shimshai in the letter, the royal reply, and the subsequent action. This reflects the verse-level presentation rather than a lexical translation.
