John Wesley on Joshua 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.
