Leviticus 14:6-7

6The priest will take the other bird and the wood from the cedar tree. He will take the red wool and the hyssop. He will put all of them into the blood of the dead bird.

7The priest will shake the blood over the person who had the disease. He will do this seven times. The priest will then say that the person is clean. The priest will let the live bird go. It will fly away.
