(48) The plague hath not spread.--If at the end of the second week's quarantine the distemper has not spread, having been checked by the means prescribed in Leviticus 14:42-43, the priest is to declare it clean, and fit for re-habitation. This is the same criterion adopted in the case of leprous men and garments. (See Leviticus 13:6; Leviticus 13:58.)

Verses 48-53. - 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. verses 3, 7, 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.

14:33-53 The leprosy in a house is unaccountable to us, as well as the leprosy in a garment; but now sin, where that reigns in a house, is a plague there, as it is in a heart. Masters of families should be aware, and afraid of the first appearance of sin in their families, and put it away, whatever it is. If the leprosy is got into the house, the infected part must be taken out. If it remain in the house, the whole must be pulled down. The owner had better be without a dwelling, than live in one that was infected. The leprosy of sin ruins families and churches. Thus sin is so interwoven with the human body, that it must be taken down by death.And if the priest shall come in, and look upon it,.... That is, on the seventh day of the second week of its being shut up:

and, behold, the plague hath not spread in the house, after the house was plastered; See Gill on Leviticus 14:42,

then the priest shall pronounce the house clean; fit to be inhabited, and so no more to be shut up, but free for use as before:

because the plague is healed; the infection being wholly removed by taking out the stones, scraping, and plastering the house, and so an entire stop put to the spread of it.
