Meaning: messenger or angel
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 (compare 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).
