(Heb. tsara'ath, a "smiting," a "stroke," because the disease was regarded as a direct providential infliction). This name is from the Greek lepra, by which the Greek physicians designated the disease from its scaliness. We have the description of the disease, as well as the regulations connected with it, in Lev. 13; 14; Num. 12:10-15, etc. There were reckoned six different circumstances under which it might develop itself, (1) without any apparent cause (Lev. 13:2-8); (2) its reappearance (9-17); (3) from an inflammation (18-28); (4) on the head or chin (29-37); (5) in white polished spots (38, 39); (6) at the back or in the front of the head (40-44).
