Leviticus 14:48
And if the priest shall come in, and look upon it, and, behold, the plague hath not spread in the house, after the house was plaistered: then the priest shall pronounce the house clean, because the plague is healed. And if the priest shall come in, and look upon it, and, behold, the plague hath not spread in the house, after the house was plaistered: then the priest shall pronounce the house clean, because the plague is healed.
The verse stands within the extended directions of Leviticus 14:33-53 concerning houses affected by plague. Those directions address how such a house was to be examined, treated, and judged. They were given as part of God's instructions for maintaining cleanliness and order in connection with His service.
