Joshua narrates the Israelites' conquest of Canaan under Joshua’s leadership. It describes the crossing of the Jordan River, the fall of Jericho, and battles against various Canaanite kings. Despite victories, not all land is fully conquered, leading to future conflicts.
The book is divided into three sections: conquest, land distribution among the twelve tribes, and Joshua’s farewell speech urging faithfulness to the covenant. Joshua emphasizes divine guidance in military success and the importance of obedience.
