Mal’a-chi (my messenger) is the author of the last book in the Old Testament. Nothing is known of him beyond what may be learned from his book.
His prophecy belongs to the times of Nehemiah, near the time of Nehemiah’s second visit to Jerusalem, about b.c. 432. It was an effort to aid in the great reforms then needed. Malachi believed in a spiritual worship as the one essential of true religion. But the system of temple ritual and sacrifices was in existence, and the prophet recognizes it as a means of educating the people into the spiritual life.
