And it came to pass on the seventh day, that they rose early about the dawning of the day, and marched around the city after the same manner seven times: only on that day they marched around the city seven times.

Seventh day. The Jews say it was the sabbath; but of this there is no proof. Marcion hence took occasion to accuse God of inconsistency, as he forbad all working, and yet ordered the people to go round Jericho on a sabbath day. But Tertullian (iv. 12,) answers very well, that servile work is forbidden, and not the works of God or of religion, and God may change the ceremonial law as he thinks proper. (Calmet)
