Then you shall let your children know, saying, Israel came over this Jordan on dry land.
There are many references to the fact that all Israel crossed over the Jordan in this chapter (Joshua 4:1-5; Joshua 4:8-9; Joshua 4:12; Joshua 4:14; Joshua 4:20; Joshua 4:24). This, too, highlights the faithfulness of God to His promises to bring the whole nation into the Promised Land.
