Leviticus 14:48-50

New Century Version

⁴⁸ “Suppose after new stones and plaster have been put in a house, the priest checks it again and the mildew has not spread. Then the priest will announce that the house is clean, because the mildew is gone.

⁴⁹ “Then, to make the house clean, the priest must take two birds, a piece of cedar wood, a piece of red string, and a hyssop plant. ⁵⁰ He will kill one bird in a clay bowl containing fresh water.
