Numbers 12:10-15

10When the cloud lifted from above the tent, Miriam’s skin was leprous—it became as white as snow. Aaron turned toward her and saw that she had a defiling skin disease, 11and he said to Moses, “Please, my lord, I ask you not to hold against us the sin we have so foolishly committed. 12Do not let her be like a stillborn infant coming from its mother’s womb with its flesh half eaten away.” 13So Moses cried out to the Lord, “Please, God, heal her!” 14The Lord replied to Moses, “If her father had spit in her face, would she not have been in disgrace for seven days? Confine her outside the camp for seven days; after that she can be brought back.” 15So Miriam was confined outside the camp for seven days, and the people did not move on till she was brought back.
