10 The priests who bore the ark remained standing in the middle of the Jordan, until everything was finished that the Lord commanded Joshua to tell the people, according to all that Moses had commanded Joshua. The people crossed over in haste. 11 As soon as all the people had finished crossing over, the ark of the Lord, and the priests, crossed over in front of the people. 12 The Reubenites, the Gadites, and the half-tribe of Manasseh crossed over armed before the Israelites, as Moses had ordered them. 13 About forty thousand armed for war crossed over before the Lord to the plains of Jericho for battle.

Commentary on Joshua 4:10-19
(Read Joshua 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.
