49 And in order to make the house clean, let him take two birds and cedar-wood and red thread and hyssop; 50 And put one of the birds to death in a vessel of earth over flowing water; 51 And take the cedar-wood and the hyssop and the red thread and the living bird and put them in the blood of the dead bird and in the flowing water, shaking it over the house seven times. 52 And he will make the house clean with the blood of the bird and the flowing water and with the living bird and with the cedar-wood and the hyssop and the red thread. 53 But he will let the living bird go out of the town into the open country; so he will take away sin from the house and it will be clean.
Matthew Henry's Commentary on Leviticus 14:49-53
Commentary on Leviticus 14:33-53
(Read Leviticus 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.
