The ceremony of cleansing the house is as similar to that of cleansing the leper as circumstances will permit. In case there is no reappearance of the mischief after the new stones and plastering have been put in, the priest shall pronounce the house clean, because the plague is healed.
First, the priest assures himself that the plague is healed, then he pronounces the house clean, and still after that the cleansing is to take place (cf. Leviticus 14:3, Leviticus 14:7, Leviticus 14:8).
The cleansing is effected by the same ceremony as that of the leper himself, by the two birds, and cedar wood, and scarlet, and hyssop. The use of this ceremony in the cleansing of a house shows that, in the case of the leper, the symbolical meaning of letting go the living bird out of the city into the open fields cannot be, as has been maintained, the restoration of the cleansed man to his natural movements of liberty in the camp.
If a bird's flight represents the freedom of a man going hither and thither as he will, it certainly does not represent any action that a house could take.
