a skin disease: The Hebrew word tsaraʿat refers to more than Hansen’s disease (leprosy), which is rare and severely disfiguring. In Leviticus, the word describes many different conditions. These include:
an open sore (13:10),
a boil (13:18),
a burn (13:24),
a sore on the head or chin (13:29),
shiny white patches (13:38), or
unusual baldness (13:40).
A key test was whether the condition spread to other parts of the body (13:5–8). If it did, they quarantined the person while the disorder lasted (13:46). Not only people, but also clothing and even buildings could become infected (13:47–59; 14:33–53).
