Regem-melech in the Bible Encyclopedia - ISBE
re'-gem-me'-lek, re'-gem-mel'-ek (reghem melekh): One of a deputation sent to inquire concerning the propriety of continuing the commemoration of the destruction of the temple by holding a fast (Zec 7:2). The text of the passage is in disorder. The name may mean "friend of the king"; hence, some have sought to remove the difficulty by interpreting reghem melekh as a title, not a personal name, reading the clause, "They of Beth-el had sent SHAREZER (q.v. (2)), the friend of the king."Read More about Regem-melech in the Bible Encyclopedia - ISBE
