Leviticus 14:6-7

MLV(i) 6 As for the living bird, he will take it and the cedar wood and the scarlet and the hyssop and will dip them and the living bird in the blood of the bird that was killed over the running water. 7 And he will sprinkle seven times upon he who is to be cleansed from the leprous disease and will pronounce him clean and will let the living bird go into the open field.
