'Defilement' in the Bible

And he shall take, to purge the house from the defilement, two birds, and cedar-wood, and scarlet, and hyssop;

and he shall purge the house from the defilement with the blood of the bird, and with the running water, and with the living bird, and with the cedar-wood, and with the hyssop, and with the scarlet;

Arise ye, and depart; for this is not the resting-place, because of defilement that bringeth destruction, even a grievous destruction.
