The Ten Commandments are repeated once again (Deuteronomy 5: 7-21).
The setting aside of the tribe of Levi to work for the Lord and not to have land portions in the Promised Land was described (Deuteronomy 10: 8-9). Once again, what to eat and not to eat are set out (Deuteronomy 14: 3-21). The rule that every 7 years people must "cancel debts" (Deuteronomy 15: 1) was mentioned -- called the Year of Release. Moses' instructions to set up three Cities of Refuge (Deuteronomy 19:2-3) is as in the Numbers' account. The rule for anyone who is a false witness against someone was given as: "...life for life, eye for eye, tooth for tooth, hand for hand, foot for foot." (Deuteronomy 19:21). It was pointed out that cross-dressing was wrong for either sex (Deuteronomy 22: 5). Moses, at 120 years old, was instructed by God to go to Mount Nebo (the Abirim mountains) in the land of Moab across from Jericho and view Canaan (the Promised Land), after which he should die. The Lord buried him in a valley near Beth Peor in Moab in an unknown place.
