Leviticus 14:37

Paleness. Hebrew, "greenish." (Haydock) --- Such spots are often observable in damp churches and cloisters, and cause the plaster to fall off. It is probable that little worms produce this effect. To prevent these vermin from spreading, Moses orders the whole house to be demolished and carried away, if it cannot be otherwise purified. (Calmet) --- Thus the plague is communicated not only by persons, but also by all the things which they have touched. The same signs of leprosy are found both in men and in houses. (Menochius)
