2 Kings 5:26
And he said unto him, 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?
Elisha knew by divine revelation that Gehazi had secretly pursued Naaman after Naaman turned from his chariot to meet him, and he knew every detail of their meeting despite Gehazi's lie that he had gone nowhere. His question exposed the lie and confronted Gehazi with what had been hidden, for Gehazi could deceive people but he could not hide his words and actions from God, who sees hidden deeds. The meaning of the question was that this was no time to enrich himself and seek wealth, no time to receive money and garments and to deceive Naaman to obtain a reward. It was no time to accept money, clothing, land, livestock and servants — money, garments, oliveyards, vineyards, sheep, oxen, menservants and maidservants.
Gehazi had coveted the gifts Elisha had refused and spoke falsehood to obtain them, mingling sacred service with selfish gain. Falsehood and deception of every kind is sin against the God of truth and is evil in His sight, and Gehazi's greedy deceit in this matter was without excuse. By his conduct he put a stumbling block in Naaman's path just as Naaman was becoming favorably disposed to serve the living God, making a servant of God a hindrance to one newly receptive to the truth.
For lying for covetous gain Gehazi was struck with Naaman's leprosy to cling to him and to his descendants. He remained a leper until his death under God's curse and shunned by others, even though he had lived with Elisha and witnessed a godly life. His corruption in handling sacred things stands as a warning that such selfishness harms God's cause.
