Leviticus 14:6, 14, 25, 51-52

Then he will take the living bird, the piece of cedar wood, the red string, and the hyssop; all these he will dip into the blood of the bird that was killed over the fresh water.

“The priest will take some of the blood of the penalty offering and put it on the bottom of the right ear of the person to be made clean. He will also put some of it on the thumb of the person’s right hand and on the big toe of the person’s right foot.

Then he will kill the lamb of the penalty offering, take some of its blood, and put it on the bottom of the right ear of the person to be made clean. The priest will put some of this blood on the thumb of the person’s right hand and some on the big toe of the person’s right foot.

Then he will take the bird that is still alive, the cedar wood, the hyssop, and the red string, and he will dip them into the blood of the bird that was killed over the fresh water. The priest will sprinkle the blood on the house seven times. He will use the bird’s blood, the fresh water, the live bird, the cedar wood, the hyssop, and the red string to make the house clean.
