10 The priests who were carrying the Ark stood in the middle of the river until all of the Lord 's commands that Moses had given to Joshua were carried out. Meanwhile, the people hurried across the riverbed. 11 And when everyone was safely on the other side, the priests crossed over with the Ark of the Lord as the people watched. 12 The armed warriors from the tribes of Reuben, Gad, and the half-tribe of Manasseh led the Israelites across the Jordan, just as Moses had directed. 13 These armed men-about 40,000 strong-were ready for battle, and the Lord was with them as they crossed over to the plains of Jericho.

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.
