2 Kings 5
16 Ref But he said, By the life of the Lord whose servant I am, I will take nothing from you. And he did his best to make him take it but he would not.
17 Ref Then Naaman said, If you will not, then let there be given to your servant as much earth as two beasts are able to take on their backs; because from now on, your servant will make no offering or burned offering to other gods, but only to the Lord.
