अपाम् अह दिव्यानाम् अपां स्रोतस्यानाम् । अपाम् अह प्रणेजने ऽश्वा भवथ वाजिनः ॥४॥
apām aha divyānām apāṃ srotasyānām | apām aha praṇejane 'śvā bhavatha vājinaḥ ||4||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Of the waters indeed from the sky, of the waters from the streams (srotasyà)—in the forth-washing indeed of the waters, ye become vigorous (vājín) horses.
Translated by William Dwight Whitney (1905)
