Leviticus 14:49-52

49He is to take two birds, cedar wood, scarlet yarn, and hyssop to purify the house; 50and he shall slaughter one of the birds over fresh water in a clay pot.

51Then he shall take the cedar wood, the hyssop, the scarlet yarn, and the live bird, dip them in the blood of the slaughtered bird and the fresh water, and sprinkle the house seven times. 52And he shall cleanse the house with the bird’s blood, the fresh water, the live bird, the cedar wood, the hyssop, and the scarlet yarn.
