Cleanse the house - Strictly, "purge the house from sin." The same word is used in Leviticus 14:52; and in Leviticus 14:53 it is said, "and make an atonement for it." Such language is used figuratively when it is applied to things, not to persons. The leprosy in houses, the leprosy in clothing, and the terrible disease in the human body, were representative forms of decay which taught the lesson that all created things, in their own nature, are passing away, and are only maintained for their destined uses during an appointed period, by the power of Yahweh.

And he shall take to cleanse the house,.... The priest, or by his fellow priest, as Aben Ezra, though some interpret it of the master of the house; in Leviticus 14:49, an account is given of the manner of cleansing a leprous house, which is the same with that of cleansing a leprous man, see notes on Leviticus 14:4-7,

Two birds. The birds here indeed are not described as "alive and clean", Leviticus 14:4; but both are plainly implied and the house is said to be cleansed with the blood of the slain bird, as well as with the living bird; and it was the upper door post of the house which was sprinkled seven times with it, but there were no sacrifices offered; in this case, as in the cleansing of the leper, the atonement for it was made by the other rites, which were sufficient to render it habitable again, and free for use, either of the owner or any other person:

and cedar wood, and scarlet, and hyssop. See Gill on Leviticus 14:4.

And he shall take to cleanse the house two birds, and cedar wood, and {o} scarlet, and hyssop:

(o) It seems that this was a lace or string to bind the hyssop to the wood, and so was made a sprinkle: the apostle to the Hebrews calls it scarlet wool, He 9:19.

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.
