John Gill Commentary 2 Kings 5:25

"But he went in, and stood before his master. And Elisha said unto him, Whence comest thou, Gehazi? And he said, Thy servant went no whither." — 2 Kings 5:25 (ASV)

But he went in, and stood before his master
To know his will, and minister to him, as he had used to do, and as if he had never been from the house:

and Elisha said unto him, from where do you come, Gehazi ?
where had he been, and where was he last?

and he said, your servant went nowhere ;
he pretended he has never been out of doors, which was another impudent lie; one would have thought that he who has lived so long with the prophet, and had seen the miracles wrought by him, and knew with what a spirit of prophecy he was endowed, would never have ventured to tell such an untruth, since he might expect to be detected; but covetousness had blinded his eyes and hardened his heart.
