Leviticus 14:49-51

New Catholic Bible

⁴⁹ He shall obtain two birds, cedar wood, scarlet yarn, and hyssop to ritually purify the house. ⁵⁰ He shall kill one of the birds over fresh water that is in a clay pot. ⁵¹ Then he shall take the cedar wood, the scarlet yarn, the hyssop, and the live bird, and he shall dip them into the blood of the slain bird and into the fresh water, and sprinkle the house seven times.
