Elijah said to him, “Elisha, please stay here, for the Lord has sent me to Jericho.” But he said, “As the Lord lives, and as you yourself live, I will not leave you.” So they came to Jericho.

Then Elijah said to him, “Please stay here, for the Lord has sent me to the Jordan.” And he said, “As the Lord lives, and as you yourself live, I will not leave you.” So the two of them went on.

The mother of the lad said, “As the Lord lives and as you yourself live, I will not leave you.” And he arose and followed her.

But he said, “As the Lord lives, before whom I stand, I will take nothing.” And he urged him to take it, but he refused.

But Gehazi, the servant of Elisha the man of God, thought, “Behold, my master has spared this Naaman the Aramean, by not receiving from his hands what he brought. As the Lord lives, I will run after him and take something from him.”
