Malachi

Malachi
    n 1: a Hebrew minor prophet of the 5th century BC [syn:
         {Malachi}, {Malachias}]
    2: an Old Testament book containing the prophecies of Malachi
       [syn: {Malachi}, {Malachias}, {Book of Malachi}]
    

Malachi
messenger or angel, the last of the minor prophets, and the
writer of the last book of the Old Testament canon (Mal. 4:4, 5,
6). Nothing is known of him beyond what is contained in his book
of prophecies. Some have supposed that the name is simply a
title descriptive of his character as a messenger of Jehovah,
and not a proper name. There is reason, however, to conclude
that Malachi was the ordinary name of the prophet.

  He was contemporary with Nehemiah (comp. Mal. 2:8 with Neh.
13:15; Mal. 2:10-16 with Neh. 13:23). No allusion is made to him
by Ezra, and he does not mention the restoration of the temple,
and hence it is inferred that he prophesied after Haggai and
Zechariah, and when the temple services were still in existence
(Mal. 1:10; 3:1, 10). It is probable that he delivered his
prophecies about B.C. 420, after the second return of Nehemiah
from Persia (Neh. 13:6), or possibly before his return.
