18 They did it. The priests carrying God's Chest of the Covenant came up from the middle of the Jordan. As soon as the soles of the priests' feet touched dry land, the Jordan's waters resumed their flow within the banks, just as before.

Matthew Henry's Commentary on Joshua 4:18

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.
