7 The Lord told Joshua, "Today I will begin to make you a great leader in the eyes of all the Israelites. They will know that I am with you, just as I was with Moses. 8 Give this command to the priests who carry the Ark of the Covenant: 'When you reach the banks of the Jordan River, take a few steps into the river and stop there.'" 9 So Joshua told the Israelites, "Come and listen to what the Lord your God says. 10 Today you will know that the living God is among you. He will surely drive out the Canaanites, Hittites, Hivites, Perizzites, Girgashites, Amorites, and Jebusites ahead of you. 11 Look, the Ark of the Covenant, which belongs to the Lord of the whole earth, will lead you across the Jordan River! 12 Now choose twelve men from the tribes of Israel, one from each tribe. 13 The priests will carry the Ark of the Lord, the Lord of all the earth. As soon as their feet touch the water, the flow of water will be cut off upstream, and the river will stand up like a wall."

Commentary on Joshua 3:7-13
(Read Joshua 3:7-13)
The waters of Jordan shall be cut off. This must be done in such a way as never was done, but in the dividing of the Red sea. That miracle is here repeated; God has the same power to finish the salvation of his people, as to begin it; the WORD of the Lord was as truly with Joshua as with Moses. God's appearances for his people ought to encourage faith and hope. God's work is perfect, he will keep his people. Jordan's flood cannot keep out Israel, Canaan's force cannot turn them out again.
