Leviticus 14:49-53 New American Bible (Revised Edition) (NABRE)
49 To purify the house, he shall take two birds, as well as cedar wood, scarlet yarn, and hyssop. 50 One of the birds he shall slaughter over an earthen vessel with fresh water in it. 51 Then, taking the cedar wood, the hyssop and the scarlet yarn, together with the living bird, he shall dip them all in the blood of the slaughtered bird and the fresh water, and sprinkle the house seven times. 52 Thus he shall purify the house with the bird’s blood and the fresh water, along with the living bird, the cedar wood, the hyssop, and the scarlet yarn. 53 He shall then let the living bird fly away over the countryside outside the city. Thus he shall make atonement for the house, and it will be clean.
