2 Kings 5

 After Naaman was healed of leprosy and Elisha refused any compensation for his service, "Gehazi, the servant of Elisha the man of God" - 

"...followed after Naaman. And when Naaman saw him running after him, he lighted down from the chariot to meet him, and said, Is all well?

22 And he said, All is well. My master hath sent me, saying, Behold, even now there be come to me from mount Ephraim two young men of the sons of the prophets: give them, I pray thee, a talent of silver, and two changes of garments."  (2 Kings 5:21–22)

It becomes obvious that Gehazi was not telling the truth for after Naaman provided Gehazi's request for -

"...when he came to the tower, he took them from their hand, and bestowed them in the house: and he let the men go, and they departed."  (2 Kings 5:24)

Elisha knew of this deception for he asks Gehazi - 

"...Went not mine heart with thee, when the man turned again from his chariot to meet thee? Is it a time to receive money, and to receive garments, and oliveyards, and vineyards, and sheep, and oxen, and menservants, and maidservants?"  (2 Kings 5:26)

Sadly, Elisha tells the selfish Gehazi - 

"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."  (2 Kings 5:27)

There should be no greed in the Lord's service.
