Malachi is the last book of the Old Testament and belongs to the period of Nehemiah. The prophets message is to the priests and the people, charging them with indifference, doubt, and immorality. Malachi tells of the coming day of the Lord and closes the book with a prophecy of John the Baptist.

Malachi 4

4:1 For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the LORD of hosts, that it shall leave them neither root nor branch.
