Commentaries
4:10-19 The priests with the ark did not stir till ordered to move. Let none be weary of waiting, while they have the tokens of God's presence with them, even the ark of the covenant, though it be in the depths of adversity. Notice is taken of the honour put upon Joshua. Those are feared in the best manner, and to the best purpose, who make it appear that God is with them, and that they set him before them.
Jos 4:14-24. God Magnifies Joshua.
14-17. On that day the Lord magnified Joshua in the sight of all Israel—It appeared clear from the chief part he acted, that he was the divinely appointed leader; for even the priests did not enter the river or quit their position, except at his command; and thenceforward his authority was as firmly established as that of his predecessor.
