So Miriam was shut up outside the camp seven days: See the comments on the previous verse.

And the people did not set out on the march till Miriam was brought in again: This sentence implies that the cloud of the LORD did not move either until Miriam returned to the camp. The lesson of her act of rebellion would have to sink in for a week. For the Hebrew verb rendered set out on the march, see the comments on 2.9.
