7 Moses was 120 years old when he died. His eyesight wasn’t impaired, and his vigor hadn’t diminished a bit.
8 Back down in the Moabite plains, the Israelites mourned Moses’ death for thirty days. At that point, the time for weeping and for mourning Moses was over.
9 Joshua, Nun’s son, was filled with wisdom because Moses had placed his hands on him. So the Israelites listened to Joshua, and they did exactly what the Lord commanded Moses.
