'Cleanse' in the Bible

To cleanse the house he shall take two birds, and cedar wood, and scarlet, and hyssop.

He shall cleanse the house with the blood of the bird, and with the running water, with the living bird, with the cedar wood, with the hyssop, and with the scarlet;

He shall sprinkle some of the blood on it with his finger seven times, and cleanse it, and make it holy from the uncleanness of the children of Israel.

for on this day shall atonement be made for you, to cleanse you; from all your sins you shall be clean before Yahweh.
