Leviticus 14:48 DBY

⁴⁶  And he that goeth into the house as long as it is shut up shall be unclean until the even.

⁴⁷  And he that sleepeth in the house shall wash his garments, and he that eateth in the house shall wash his garments.

⁴⁸  But if the priest shall come in and look, and behold, the plague hath not spread in the house, after the house hath been plastered, the priest shall pronounce the house clean; for the plague is healed.

⁴⁹  And he shall take, to purge the house from the defilement, two birds, and cedar-wood, and scarlet, and hyssop;

⁵⁰  and he shall kill one bird in an earthen vessel over running water;
