The Book of Deuteronomy begins in the final, fortieth year of Israel's wandering in the desert. Stationed east of the Jordan River, Moses addresses the new generation of Israelites in preparation for entering the promised land. He summarizes the events of the past four decades and encourages the young Israelites to remember God's miracles and covenant with Israel. He forbids the worship of other gods or idols in the new land and repeats the Ten Commandments given by God at Mount Sinai. Most importantly, Moses gives explicit instructions to the Israelites to destroy all the native inhabitants of the promised land so that the Canaanites do not interfere with Israel's worship of God. Moses restates many of the social laws and rules of conduct outlined in Leviticus, adding a few new laws, such as the requirement for the Israelites to cancel debts every seven years.
