Take heed in the plague of leprosy, that you observe diligently, and do according to all that the priests the Levites shall teach you…
I. A JUDGMENT TO BE DREADED. Leprosy is viewed here, as usually in Scripture:
1. As a stroke of Divine judgment. It was not always such (Job 2.). Nor did the stroke of Divine judgment always take this form (Uzzah, Jeroboam, Ananias, etc.). But it was a frequent form of punishment for sins of a theocratic nature (Uzziah, Gehazi, etc.). It is seldom safe to interpret judgments (Luke 13:1-6), but we may expect God's stroke in some way to fall upon ourselves if we persistently despise his laws.
2. As a symbol of spiritual corruption. The worst penalty with which God can visit any one is to smite him with soul leprosy, to leave sin to have its natural dominion over him, to allow its corruption to work and spread through his inner man.
II. A WARNING TO BE PONDERED. They are bid remember the case of Miriam. We do well to lay to heart the instances we have known of sin working out punishment and death. Miriam's case suggests the additional thought of pardon on repentance, and of the prevalence of intercession in obtaining forgiveness for offences (Numbers 12:9-16). - J.O.
