Hey look, it’s the final book of the Old Testament! Malachi is only 4 chapters long, but boy does it give us one final thwack of cuckoo across the face to close things out. From God’s anger at his people divorcing their spouses and offering him unsavory animal sacrifices to God threatening to smear poo on his people’s faces, Malachi really ends the Old Testament with a bang and a smash (of poo in your face).
It seems that less is known about Malachi than any of the minor prophets thus far. According to Wikipedia: “Although the appellation Malachi has frequently been understood as a proper name, its Hebrew meaning is simply ‘My [i.e., God’s] messenger’ (or ‘His messenger’ in the Septuagint) and may not be the author’s name at all.” So, not only do we have no idea when this book was written or what the context is, we don’t even know who this book’s author was or whether Malachi was even his name. Super!
