3:13 The ark of the Lord - That so it may appear this is the Lord's doing, and that in pursuance of his covenant made with Israel. Of all the earth - The Lord of all this globe of earth and water, who therefore can dispose of this river and the adjoining land as he pleaseth. Cut off - The waters which now are united now shall be divided, and part shall flow down the channel towards the dead sea, and the other part that is nearer the spring of the river, and flows down from it, shall stand still. An heap - Being as it were congealed, as the Red - Sea was, Exod 15:8, and so kept from overflowing the country.
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.
