Joshua 4:9

5 and said to them, “Cross over before the ark of the LORD your God into the middle of the Jordan. Each of you is to take a stone upon his shoulder, according to the number of the tribes of Israel,

6 to serve as a sign among you. In the future, when your children ask, ‘What do these stones mean to you?’

7 you are to tell them, ‘The waters of the Jordan were cut off before the ark of the covenant of the LORD. When it crossed the Jordan, the waters were cut off.’ Therefore these stones will be a memorial to the Israelites forever.”

8 Thus the Israelites did as Joshua had commanded them. They took up twelve stones from the middle of the Jordan, one for each tribe of Israel, just as the LORD had told Joshua; and they carried them to the camp, where they set them down.

9 Joshua also set up twelve stones in the middle of the Jordan, in the place where the priests who carried the ark of the covenant stood. And the stones are there to this day.

10 Now 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,

11 and after everyone had finished crossing, the priests with the ark of the LORD crossed in the sight of the people.

12 The Reubenites, the Gadites, and the half-tribe of Manasseh crossed over before the Israelites, armed for battle as Moses had instructed them.

13 About 40,000 troops armed for battle crossed over before the LORD into the plains of Jericho.
