The answer is: Moses

Deut 1:1

Moses is indeed the main narrator in Deuteronomy, but this isn't just a dry retelling of laws and history; it’s more like an emotional pep talk from a loving leader to his people. Imagine Moses standing on the brink of the Promised Land, knowing he may not enter it himself. This formula for a heartfelt farewell stirs the heart. Through his speeches, Moses reminds the Israelites not only of the laws but of their identity and divine journey, emphasizing faithfulness, community, and remember who they are.

Interestingly, the name “Deuteronomy” itself means "second law," effectively double-checking previous commands and expanding on them for a new generation. It’s reminiscent of parents wanting to ensure their children grasp the key lessons learned through experience.

Fun fact: Deuteronomy is structured with a series of speeches covering various topics. Chapters like the Shema (Deut 6:4-5) encapsulate the importance of loving one's God wholeheartedly. It also draws upon echoes from previous writings, creating a rich tapestry that reflects the culture and legal systems of surrounding ancient nations and leading the Israelites to distinctiveness.

Think also of the covenant for blessings or curses based on obedience (Deut 28), a theme that resonates beyond ancient times into modern reflections of ethical living. Moses doesn't just give laws; he's pouring spirit into those laws, anchoring civil life within a sacred purpose.
