Malachi appears last in the Old Testament and is chronologically toward the end of the period, the prophet possibly being a contemporary of Ezra and Nehemiah. By this time, the Jewish people had been back in Israel for some time and they were losing their zeal for God.
Malachi called out the people on many of the ways they neglected God and their calling to be His people. They offered substandard sacrifices. They married foreigners who worshipped false gods. They refused to tithe. They were envious of other nations. Even the priests were complicit in the sins of the people.
He warned of a judgment coming. There was hope for the faithful; their always is for those who trust God.
