Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 32

Sanskrit:

दुर्जरं बत ब्रह्मस्वं भुक्तमग्नेर्मनागपि ।तेजीयसोऽपि किमुत राज्ञां ईश्वरमानिनाम् ॥ ३२ ॥

ITRANS:

durjaraṁ bata brahma-svaṁbhuktam agner manāg apitejīyaso ’pi kim utarājñāṁ īśvara-māninām

Translation:

[Lord Kṛṣṇa said:] How indigestible is the property of a brāhmaṇa, even when enjoyed just slightly and by one more potent than fire! What then to speak of kings who try to enjoy it, presuming themselves lords.

Purport:

Even those made powerful by austerity, mystic yoga and so on cannot enjoy property stolen from a brāhmaṇa, and what to speak of others.
