Bhagavad Gita 3.12

इष्टान्भोगानहि वो देवा दास्यन्ते यज्ञभाविता: |
तैरदत्तानप्रदायैभ्यो यो भुक्त्ते स्तेन एव स:

Translation

The celestial gods, being satisfied by the performance of sacrifice, will grant you all the desired necessities of life. But those who enjoy what is given to them, without making offerings in return, are verily thieves.
