Joshua was known as “The son of Nun” of the tribe of Ephraim and Moses’ successor. Moses sent 12 men to spy on Canaan, the “Promised Land,” (Num 13:17), but Joshua and Caleb were the only two who gave an encouraging report and were rewarded with permission to enter Israel with the new generation of Israelites, the rest of the original Israelites died in the wilderness.
Joshua and his army crossed the Jordan and the battle began. After taking Jericho, in which God destroyed the walls (Josh 6:1-21), there were three campaigns fought. One in the north, one in the central region, and one interview the south. It took seven years of war to conquer the land and drive out most of the Hittites, Amorites, Canaanites, Perizzits, Hivites, and Jebusites. Thirty-one kinds and their cities were destroyed by Joshua and his army (Josh 7-12). After the initial victories the land was divided among the tribes of Israel (Josh 13-17).
At an old age Joshua made a covenant with the people of Israel at Shechem, committing them to a permanent and binding contract between themselves and God. Soon after, at the age of 110, he died and was buried on his own estate at Timnath-sereh in Ephraim (Josh 24:29).
The Israelites obeyed God throughout the lifetime of Joshua.
The story of Joshua is found in Genesis 34:9-12 and the book of Joshua.
