Now, carefully obey all the commands of the Lord your God. Carefully obey all his laws and commands and decisions and agreements. Obey everything that is written in the Law of Moses. If you do this, then you will be successful in everything you do and every place you go.
So Moses gave that land to the people of Gad, to the people of Reuben, and to half of Manasseh’s family group. (Manasseh was Joseph’s son.) That land included the kingdom of Sihon the Amorite and the kingdom of Og, king of Bashan. That land included all the cities around that area.
You must live the way the Lord your God commanded you. Then you will continue to live, and everything will be fine with you. You will live a long life in the land that will belong to you.
But you must also be strong and brave about another thing. You must be sure to obey the commands my servant Moses gave you. If you follow his teachings exactly, then you will be successful in everything you do.
Always remember the things written in that book of law. Study that book day and night. Then you can be sure to obey the things that are written there. If you do this, then you will be wise and successful in everything you do.
