This was used to cover the walls of houses (Lev. 14:42-4842And they shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house. 43And if the plague come again, and break out in the house, after that he hath taken away the stones, and after he hath scraped the house, and after it is plaistered; 44Then the priest shall come and look, and, behold, if the plague be spread in the house, it is a fretting leprosy in the house: it is unclean. 45And he shall break down the house, the stones of it, and the timber thereof, and all the mortar of the house; and he shall carry them forth out of the city into an unclean place. 46Moreover he that goeth into the house all the while that it is shut up shall be unclean until the even. 47And he that lieth in the house shall wash his clothes; and he that eateth in the house shall wash his clothes. 48And 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. (Leviticus 14:42‑48); Dan. 5:55In the same hour came forth fingers of a man's hand, and wrote over against the candlestick upon the plaster of the wall of the king's palace: and the king saw the part of the hand that wrote. (Daniel 5:5)); and was also spread on large stones, on which the law could be inscribed (Deut. 27:2-42And it shall be on the day when ye shall pass over Jordan unto the land which the Lord thy God giveth thee, that thou shalt set thee up great stones, and plaster them with plaster: 3And thou shalt write upon them all the words of this law, when thou art passed over, that thou mayest go in unto the land which the Lord thy God giveth thee, a land that floweth with milk and honey; as the Lord God of thy fathers hath promised thee. 4Therefore it shall be when ye be gone over Jordan, that ye shall set up these stones, which I command you this day, in mount Ebal, and thou shalt plaster them with plaster. (Deuteronomy 27:2‑4); Josh. 8:3232And he wrote there upon the stones a copy of the law of Moses, which he wrote in the presence of the children of Israel. (Joshua 8:32)). It may have been compounded of different substances for divers purposes.
