Command the priests that bear the ark of the testimony,.... In all places before, in this history, the ark is called the ark of the covenant, here the ark of the testimony, which signifies the same thing, the law; which was both the covenant between God and the people, and a testimony of his will unto them; the Septuagint version has both words:

that they come up out of Jordan; where they stayed until all the people passed over, for the encouragement of them, and until they received this order.

Command the priests that bear the {g} ark of the testimony, that they come up out of Jordan.

(g) Because the ark testified God's presence, and the tables of the Law contained in it signified God's will toward his people.

4:16 Out of Jordan - For being now in the middle, and deepest place of the river, they are most properly said to go up to the land.

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.
