Matthew Poole and continuators on 2 Kings 5:27

27 The leprosy therefore of Naaman shall cleave unto thee, and unto thy seed for ever . And he went out from his presence a leper as white as snow .

i. e. For some Generations; or for a long time, as that World is oft used, and as may be thought by comparing this with Exod. 20. 55. and 34. 7.

Being confounded with the sense of his guilt, and shame, and misery, and banished from the company of others by God's Law, Levit. 13. and 14.

Which is the worst kind of Leprosie, and noted by Physitians to be incurable. See Exod. 4. 6. Numb. 12. 10. 2 Chron. 26. 19, 20. Nor was this Punishment too severe for Gehazi's Wickedness, which was great, and various, horrid Covetousness, which is Idolatry; the Prophanation of God's Name, by a Wicked Oath; downright Theft; deliberate and impudent Lying, and that to a Prophet, which was in a manner a lying to the holy Ghost, like theirs, Acts 5. 3. A desperate contempt of God's Omniscience, Justice, and Holiness; an horrible Reproach fastned upon the Prophet, and his Religion; and a mischievous Scandal given to Naaman and all other Syrians that might hear of it.
