II Kings 4:13

"And he said to him, 'Say now to her, "Look, you have been concerned for us with all this care. What can I do for you? Do you want me to speak on your behalf to the king or to the commander of the army?" She answered, "I dwell among my own people".'"

(Her response here is her showing contentment. She needs nothing from Elisha, she just wants to serve him. Even though Elisha does give her something in return for all her deeds. God rewards you when you're content. He gives us all we need.)
