Atharvaveda Samhita — Kanda 19 — Chapter 41
AV 19 41.1
भद्रम् इछन्त ऋषयः स्वर्विदस् तपो दीक्षाम् उपनिषेदुर् अग्रे । ततो राष्ट्रं बलम् ओजश् च जातं तद् अस्मै देवा उपसंनमन्तु
bhadram ichanta ṛṣayaḥ svarvidas tapo dīkṣām upaniṣedur agre | tato rāṣṭraṃ balam ojaś ca jātaṃ tad asmai devā upasaṃnamantu
Seeking what is auspicious, the seers, finders of the light, sat down in the beginning to ascetic heat and consecration. From that were born kingship, strength and vigour; let the gods make that bend toward him.

Compare with Ralph T.H. Griffith
Desiring bliss, at first, light-finding Rishis began religious rite and holy fervour. Thence energy was born, and might, and kingship: so to this man let gathered Gods incline them.
— tr. Ralph T.H. Griffith (1895–96)
