BṚHADĀRAṆYAKA UPANISHAD · 2.1.1

दृप्तबालाकिर् हानूचानो गार्ग्य आस ।
स होवाचाजातशत्रुं काश्यं -- ब्रह्म ते ब्रवाणीति ।
स होवाचाजातशत्रुः -- सहस्रम् एतस्यां वाचि दद्मः, जनको जनक इति वै जना धावन्तीति ॥

dṛptabālākir hānūcāno gārgya āsa ।
sa hovācājātaśatruṃ kāśyaṃ -- brahma te bravāṇīti ।
sa hovācājātaśatruḥ -- sahasram etasyāṃ vāci dadmaḥ, janako janaka iti vai janā dhāvantīti ॥

There was formerly the proud Gârgya Bâlâki, a man of great reading. He said to Agâtasatru of Kâsi, 'Shall I tell you Brahman?' Agâtasatru said: 'We give a thousand (cows) for that speech (of yours), for verily all people run away, saying, Ganaka (the king of Mithilâ) is our father (patron).'
