Leviticus 14:47-49

⁴⁷And he who may sleep in the house shall wash his clothes, and he who eateth in the house shall wash his clothes.

⁴⁸But if the priest, having entered, shall look, and, behold, the plague hath not increased in the house after the house hath been plastered, the priest shall make (pronounce) the house to be clean, for the plague hath been cured.

⁴⁹And he shall take, to purify the house, two birds, and cedar wood, and scarlet, and hyssop.
