Numbers 12:13-15

Moses cried out to the LORD, saying, “O God, heal her, I pray!” But the LORD said to Moses, “If her father had but spit in her face, would she not bear her shame for seven days? Let her be shut up for seven days outside the camp, and afterward she may be received again.” So Miriam was shut up outside the camp for seven days, and the people did not move on until Miriam was received again.
