Leviticus 14:51-53

Expanded Bible

⁵¹ 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 [slaughtered] over the fresh water. The priest will sprinkle the blood on the house seven times. ⁵² 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. ⁵³ He will then go to an open field outside the city and let the living bird go free. This is how the priest makes the house clean and ·ready for service to the Lord [makes atonement for the house].”
