Leviticus 14:47-49

⁴⁷Anyone who sleeps in that house or eats in that house during that time must wash his clothes.

⁴⁸But when the priest comes to examine the house after it has been plastered, if the mildew has not spread, he shall declare that people may live in it, because the mildew is gone.

⁴⁹But before people are allowed to live in it, the priest must take two small birds and some cedar wood and some red/scarlet yarn and some hyssop.
