Leviticus 13:56-59
burn up <08313> [shalt burn.]
wash .......... washed <03526> [be washed.]
The plague of leprosy was inflicted immediately from the hand of God, and came not from natural causes, as other diseases; and therefore must be managed according to a divine law. Miriam's leprosy, and Gehazi's and King Uzziah's were all the punishments of particular sins; and if generally it was so, no marvel there was so much care taken to distinguish it from a common distemper, that none might be looked upon as lying under this extraordinary token of Divine displeasure, but those that really were so.
