Malachi 4:4

Moses’ last words to the Israelites in Deuteronomy contain about 14 exhortations to remember the Law that God had given them. Malachi closed his book, and God closed the Old Testament, with the same exhortation. One writer identified nine connections between Malachi and the Book of Deuteronomy. [Note: Hugenberger, pp. 48-50.] Although the Hebrew canon ends with Chronicles rather than Malachi, Malachi concludes the Prophets section of the Hebrew Bible. The Jews regarded "the Law and the Prophets" as comprising their entire Scriptures (cf. Matthew 5:17; Matthew 7:12; Matthew 11:13; Matthew 22:40; Luke 16:16; John 1:45; Acts 13:15; Acts 24:14; Acts 28:23; Romans 3:21).

The Israelites had forgotten and disregarded God’s law, and Malachi had pointed out many specific instances of that. Now he urged the people to recall and obey their Law. By calling Moses "My servant," the Lord was reminding Malachi’s audience of how faithful Moses had carried out God’s will. He was to be their model of obedience. The Law of Moses (i.e., the Pentateuch) was still God’s word to His people after all that had happened to them.
