Mahabharata — Anushasana Parva, Shloka 11
Gaṅgā-māhātmya: Siddha–Śilavṛtti-saṃvāda and Gaṅgā-stava (गङ्गामाहात्म्यं—सिद्ध-शिलवृत्ति-संवादः)
“जो पापपरायण मूढ़ मनुष्य ब्राह्मणोंको अकारण ही मर्मभेदी शोक प्रदान करता है, उसे ब्रह्मघाती जाने ।।
bhīṣma uvāca | yo pāpaparāyaṇaḥ mūḍhaḥ manuṣyo brāhmaṇān akāraṇam eva marmabhedīṃ śokaṃ pradadāti, taṃ brahmaghātī jānīyāt || cakṣuṣā viprahīṇasya paṅgulasya jaḍasya vā | haret yo vai sarvasvaṃ taṃ vidyād brahmaghātinam ||
毗湿摩说道：愚迷而趋向罪恶之人，若无故使婆罗门遭受刺心入髓的悲苦，当知其为婆罗门杀害者（brahma-ghātin）。同样，凡夺取盲者、跛者，或无助而愚钝之人的全部生计与财物者，也当知其为 brahma-ghātin。

Educational Q&A
Deliberately causing unjustified, deep suffering to Brahmins, and exploiting those who are physically or mentally helpless by taking their entire livelihood, are treated as among the gravest moral offenses—classified here as brahma-ghāta (a sin comparable in severity to brahmahatyā).
In Anushasana Parva’s instruction on dharma, Bhishma is laying down ethical standards for conduct: he condemns gratuitous cruelty toward the spiritually venerable and predatory theft from the defenseless, marking both as extreme adharma.
