23 For the LORD your God dried up the waters of the Jordan from before you until you had crossed over, as the LORD your God did to the Red Sea, which he dried up from before us, until we had crossed over,
24 that all the peoples of the earth may know that the LORD’s hand is mighty, and that you may fear the LORD your God forever.’”
