How many times did the Israelite cross the Jordan river?

The Israelites crossed the Jordan River twice. The first crossing occurred when they entered the Promised Land under Joshua's leadership, as recounted in the Book of Joshua, when the waters of the river were miraculously parted. The second crossing happened later when they returned to the eastern side of the Jordan for various reasons, including the allocation of land to the tribes of Reuben, Gad, and half of Manasseh.
