Portion for Reading Deut 29-31Msg: Deuteronomy 31:1-8
Then Moses went out and spoke these words to all Israel: "I am now a hundred and twenty years old and I am no longer able to lead you. The LORD has said to me, 'You shall not cross the Jordan.' The LORD your God himself will cross over ahead of you. He will destroy these nations before you, and you will take possession of their land. Joshua also will cross over ahead of you, as the LORD said. And the LORD will do to them what he did to Sihon and Og, the kings of the Amorites, whom he destroyed along with their land. The LORD will deliver them to you, and you must do to them all that I have commanded you. Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you."
Then Moses summoned Joshua and said to him in the presence of all Israel, "Be strong and courageous, for you must go with this people into the land that the LORD swore to their forefathers to give them, and you must divide it among them as their inheritance. The LORD himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged
Finally it comes time for Moses to choose a successor in Numbers 27:18-23.
"So the LORD said to Moses, 'Take Joshua son of Nun, a man in whom is the Spirit, and lay your hand on him. Have him stand before Eleazar the priest and the entire assembly and commission him in their presence. Give him some of your authority so the whole Israelite community will obey him. He is to stand before Eleazar the priest, who will obtain decisions for him by inquiring of the Urim before the LORD. At his command he and the entire community of the Israelites will go out, and at his command they will come in.'
"So the LORD said to Moses, 'Take Joshua son of Nun, a man in whom is the Spirit, and lay your hand on him. Have him stand before Eleazar the priest and the entire assembly and commission him in their presence. Give him some of your authority so the whole Israelite community will obey him. He is to stand before Eleazar the priest, who will obtain decisions for him by inquiring of the Urim before the LORD. At his command he and the entire community of the Israelites will go out, and at his command they will come in.'
"Moses did as the LORD commanded him. He took Joshua and had him stand before Eleazar the priest and the whole assembly. Then he laid his hands on him and commissioned him, as the LORD instructed through Moses" (Numbers 27:18-23).
Notice that the Spirit is already upon Joshua (vs. 18). What is new is the commission and authority to command.
