Teresh in the Bible Encyclopedia - ISBE

te'-resh (teresh (Est 2:21; 6:2); Codex Vaticanus, Codex Alexandrinus, and Codex Sinaiticus omit it; but Codex Sinaiticus' margin has Tharas and Tharras): A chamberlain of King Ahasuerus. Oppert compares the name with Tiri-dates, the name of the governor of Persepolis in the time of Alexander. Another explanation identifies it with the Persian word turs "firm"; Scheft links it with the Persian tarsha, "desire."
