Overview
Plaster served as a practical building material in ancient Israel, applied to walls for protection and preservation. The Bible mentions plaster in both ceremonial and architectural contexts, particularly regarding the inspection and treatment of diseased houses, and as a surface for inscribing God's law.
Key Scriptures
"Then the priest shall command them to take out the stones in which the disease appears and throw them into an unclean place outside the city. And he shall cause the house to be scraped inside all around, and the dust that they scrape off they shall pour out in an unclean place outside the city" (Leviticus 14:40, ESV). "If the disease breaks out again in the house, after he has taken out the stones and scraped the house and plastered it, then the priest shall go and look. And if the disease has spread in the house, it is a malignant leprous disease in the house; it is unclean" (Leviticus 14:43, ESV). "You shall write on the stones all the words of this law very plainly" (Deuteronomy 27:8, ESV).
Application
Recognize that God's attention to practical details in building and health reflects His care for our complete wellbeing, both physical and spiritual.
