RV 9.70.6
स मातरा न ददृशान उस्रियो नानदद् एति मरुताम् इव स्वनः । जानन्न् ऋतम् प्रथमं यत् स्वर्णरम् प्रशस्तये कम् अवृणीत सुक्रतुः ॥
sa mātarā na dadṛśāna usriyo nānadad eti marutām iva svanaḥ | jānann ṛtam prathamaṃ yat svarṇaram praśastaye kam avṛṇīta sukratuḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Beholding, as it were, Two Mother Cows, the Steer goes roaring on his way even as the Maruts roar. Knowing Eternal Law, the earliest light of heaven, he, passing wise, was chosen out to tell it forth.
Translated by Ralph T. H. Griffith (1896)
