Numbers 12:13-15

13And Moses cried to the Lord, "O God, please heal her—please."

14But the Lord said to Moses, "If her father had but spit in her face, should she not be shamed seven days? Let her be shut outside the camp seven days, and after that she may be brought in again."

15So Miriam was shut outside the camp seven days, and the people did not set out on the march till Miriam was brought in again.
