Book of Malachi

The Book of Malachi (Hebrew: מַלְאָכִ֔י, romanized: Malʾāḵī) is the last book of the Nevi'im in the Tanakh and canonically the final book of the Twelve Minor Prophets. In most Christian traditions, the prophetic books form the last section of the Old Testament, making Malachi the last book before the New Testament. The book has four chapters.

The author of Malachi may or may not have been identified by the title itself. While often understood as a proper name, its Hebrew meaning is simply "my messenger" (the Septuagint translates it as "his messenger"). It was not a proper name at the time of its writing. Jewish tradition states that the book was written by the Scribe Ezra.

Most scholars believe the book underwent multiple stages of redaction. The majority of its text originates in the Persian period; the oldest portions dating to c. 500 BCE. Later modifications occurred into the Hellenistic period.
