Numbers 12:14-15

¹⁴And the Lord said to Moses, If her father had put a mark of shame on her, would she not be shamed for seven days? Let her be shut up outside the tent-circle for seven days, and after that she may come in again.

¹⁵So Miriam was shut up outside the tent-circle for seven days: and the people did not go forward on their journey till Miriam had come in again.
