With hollow strakes, greenish or reddish. — If the house is really leprous, the priest on inspecting it will find in the walls the same three symptoms which are visible in the skin of leprous human beings: (1) hollow strakes, or, rather, deep cavities or depressions, which the ancient canons define as a depression deeper than the rest of the wall, being the same symptom as in man (see Leviticus 13:3); (2) a greenish or (3) a reddish spot, which were the second and third symptoms of leprosy in men and garments. (Comp. Leviticus 13:49.) According to the canons which obtained during the second Temple, the size of this discoloured spot on the wall had to be that of two beans.
