2 Kings 5:27

“The leprosy therefore of Naaman shall cleave unto thee, and unto thy seed for ever, etc.] As long as any of his race remained; as through his covetousness he had his money, so for his punishment he should have his disease: and he went out from his presence; as one ashamed and confounded, and discharged from his master’s service: a leper [as white] as snow; a leprosy of which colour is the worst, and is incurable.”

“leper as white as snow--(See on Lev 13:3). This heavy infliction was not too severe for the crime of Gehazi. For it was not the covetousness alone that was punished; but, at the same time, it was the ill use made of the prophet's name to gain an object prompted by a mean covetousness, and the attempt to conceal it by lying [KEIL]. Next: 2 Kings Chapter 6”

“For ever - That is, for some generations; as that word is often used and as may be thought by comparing this with Exo 20:55. (?)

“"And let the leprosy of Naaman cleave to thee and to thy seed for ever." This punishment took effect immediately. Gehazi went out from Elisha covered with leprosy as if with snow (cf. ex. Kg2 4:6; Num 12:10). It was not too harsh a punishment that the leprosy taken from Naaman on account of his faith in the living God, should pass to Gehazi on account of his departure from the true God. For it was not his avarice only that was to be punished, but the abuse of the prophet's name for the purpose of carrying out his selfish purpose, and his misrepresentation of the prophet. (Note: "This was not the punishment of his immoderate δωροδοκίας (receiving of gifts) merely, but most of all of his…”
