10Now the priests who carried the ark remained standing in the middle of the Jordan until the people had completed everything the LORD had commanded Joshua to tell them, just as Moses had directed Joshua. The people hurried across,
11and after everyone had finished crossing, the priests with the ark of the LORD crossed in the sight of the people.
12The Reubenites, the Gadites, and the half-tribe of Manasseh crossed over before the Israelites, armed for battle as Moses had instructed them.
— Joshua 4:10-12
