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.
48-57. the priest shall pronounce the house clean, because the plague is healed—The precautions here described show that there is great danger in warm countries from the house leprosy, which was likely to be increased by the smallness and rude architecture of the houses in the early ages of the Israelitish history. As a house could not contract any impurity in the sight of God, the "atonement" which the priest was to make for it must either have a reference to the sins of its occupants or to the ceremonial process appointed for its purification, the very same as that observed for a leprous person. This solemn declaration that it was "clean," as well as the offering made on the occasion, was admirably calculated to make known the fact, to remove apprehension from the public mind, as well as relieve the owner from the aching suspicion of dwelling in an infected house.
