Bhagavad Gita 3.12 Chapter 3, Verse 12

इष्टान्भोगान्हि वो देवा दास्यन्ते यज्ञभाविताः ।
तैर्दत्तानप्रदायैभ्यो यो भुङ्क्ते स्तेन एव सः ॥३.१२॥

iṣṭānbhogānhi vo devā dāsyante yajñabhāvitāḥ
tairdattānapradāyaibhyo yo bhuṅkte stena eva saḥ

Meaning

Pleased by sacrifice, the gods will grant you the enjoyments you desire. One who enjoys their gifts without offering anything back is simply a thief.
