⁴⁹ And ^(A)he shall take, to cleanse the house, two birds, cedar wood, scarlet, and hyssop. ⁵⁰ Then he shall kill one of the birds in an earthen vessel over running water; ⁵¹ and he shall take the cedar wood, the hyssop, the scarlet, and the living bird, and dip them in the blood of the slain bird and in the running water, and sprinkle the house seven times.
