Malachi. Malachi, Malachias, Malache or Mal'achi was the writer of the Book of Malachi, the last book of the Neviim section in the Hebrew Bible.
No allusion is made to him by Ezra, however, and he does not directly mention the restoration of the temple. The editors of the 1906 Jewish Encyclopedia implied that he prophesied after Haggai and Zechariah and speculated that he delivered his prophecies about 420 BCE, after the second return of Nehemiah from Persia, or possibly before his return, comparing Malachi 2:8 with Nehemiah 13:15.
In the Septuagint, or Greek Old Testament, the Prophetic Books are placed last, making the Book of Malachi the last protocanonical book before the Deuterocanonical books or The New Testament. According to the 1897 Easton's Bible Dictionary, it is possible that Malachi is not a proper name, but simply means messenger of YHWH.
Because Malachi's name does not occur elsewhere in the Bible, some scholars doubt whether Malachi is intended to be the personal name of the prophet. None of the other prophetic books of the Hebrew Bible or the Greek Old Testament are anonymous.
The form mal'akhi, signifies my messenger; it occurs in Malachi 3:1. But this form of itself would hardly be appropriate as a proper name without some additional syllable such as Yah, whence mal'akhiah, i.e. messenger of Elohim. Haggai, in fact, is expressly designated messenger of Elohim. Besides
