महाभारतः mahābhārataḥ - book-5, chapter-43, verse-29

विद्याद्बहु पठन्तं तु बहुपाठीति ब्राह्मणम् ।
तस्मात्क्षत्रिय मा मंस्था जल्पितेनैव ब्राह्मणम् ।
य एव सत्यान्नापैति स ज्ञेयो ब्राह्मणस्त्वया ॥२९॥

29. vidyādbahu paṭhantaṁ tu bahupāṭhīti brāhmaṇam ,
tasmātkṣatriya mā maṁsthā jalpitenaiva brāhmaṇam ,
ya eva satyānnāpaiti sa jñeyo brāhmaṇastvayā.

29. vidyāt bahu paṭhantam tu bahupāṭhī iti
brāhmaṇam tasmāt kṣatriya mā maṃsthāḥ
jalpitena eva brāhmaṇam yaḥ eva satyāt
na apaiti saḥ jñeyaḥ brāhmaṇaḥ tvayā

29. One should consider someone who studies extensively as merely a "great reciter," not as a true Brahmin. Therefore, O Kṣatriya, do not consider a person a Brahmin based solely on their words. Rather, you should know that individual to be a Brahmin who never deviates from truth (satya).
