Deuteronomy 31

Moses, now 120 years old, prepares for his death. He officially appoints Joshua as the new leader, encouraging him to be strong and courageous. Moses then writes down the entire Book of the Law and entrusts it to the priests (the sons of Levi) and the elders, commanding them to read it publicly to all Israel every seven years during the Feast of Tabernacles. God reveals to Moses that the people will inevitably become corrupt after his death.
