31:10-13 The laws were to be read to the whole assembly so that everyone, including the children, could hear them. Every seven years the entire nation would gather together and listen as a priest read the law to them. There were no books, Bibles, or newsstands to spread God’s word, so the people had to rely on word of mouth and an accurate memory. Memorization was an important part of worship because if everyone knew the law, ignorance would be no excuse for breaking it. To fulfill God’s purpose and will in our lives, we need the content and substance of his Word in our hearts and minds. For the Hebrews, this process began in childhood. Teaching our children and new believers should be one of our top priorities. Our finest teachers, best resources, and most careful thought should be directed toward showing young believers how to follow God in all life’s situations.
31:23 Joshua had been appointed to take over the leadership of Israel and guide the people into the Promised Land (Moses could not enter the land due to his disobedience—Numbers 20:12). Joshua, first mentioned in Exodus 17:9, had been Moses’ assistant for many years (Joshua 1:1). One of his key qualifications was his faith. As one of the 12 spies to first enter Canaan, only he and Caleb believed that God could help Israel conquer the land (Numbers 13:1–14:30). Moses told Joshua to be strong and of good courage twice in this chapter (31:7, 23). Indeed, this was a frightening task with three million people to care for, settle disputes for, and lead into battle. Finding courage would be Joshua’s greatest test. He was strong and courageous because he knew God was with him and because he had faith that God would do all he had promised Israel.
31:27-29 Moses knew that the Israelites, in spite of all they had seen of God’s work, were rebellious at heart. They deserved God’s punishment, although they often received his mercy instead. We, too, are stubborn and rebellious by nature. Throughout our lives we struggle with sin. Repentance once a month or once a week is not enough. We must constantly turn from our sins to God and let him, in his mercy, save us.
