Leviticus 14:48-50

New International Version

⁴⁸ “But if the priest comes to examine it and the mold has not spread after the house has been plastered, he shall pronounce the house clean,^(A) because the defiling mold is gone. ⁴⁹ To purify the house he is to take two birds and some cedar wood, scarlet yarn and hyssop.^{(B) 50} He shall kill one of the birds over fresh water in a clay pot.^(C)
