“The Lord had given rest to Israel from all their enemies” means that He gave the people the strength to establish the intention to bestow above all egoistic desires that are our enemies.
“Joshua was old” means that almost all of his egoistic intentions turned into altruistic ones. It means that Joshua, who used to fight with himself and with others, became a wise old man. Although he fulfilled his mission, he continued to lead the people until the kings of Israel replaced him.
Question: Wisdom—is that what he corrected?
Answer: Yes, that is wisdom, that is strength. But at the same time, his degree exhausted itself, and he must give way to others.
