ऋचाम् (of the Rigvedic verses) | त्वः (one/somebody) | पोषम् (nourishing/mastery) | आस्ते (sits/is occupied with) | पुपुष्वान् (prospering/increasing) | गायत्रम् (the Gayatri/Saman chant) | त्वो (another) | गायति (sings) | शक्वरीषु (in the Shakvari meters) | ब्रह्मा (the Brahma priest) | त्वो (another) | वदति (speaks/declares) | जातविद्याम् (knowledge of all that exists) | यज्ञस्य (of the sacrifice) | मात्राम् (the measure/rules) | वि मिमीते (measures out/prepares) | उ त्वः (and yet another).
Translation
One (the Hotṛ) is occupied with the mastery of the Rigvedic verses; another (the Udgātṛ) sings the Saman chants in the Shakvari meters; another (the Brahmā) declares the secret knowledge of existence; and yet another (the Adhvaryu) measures out the actual proportions of the sacrifice.
