Sanskrit text [Accents, Plain, Transliterated]:

अधा॑ मा॒तुरु॒षस॑: स॒प्त विप्रा॒ जाये॑महि प्रथ॒मा वे॒धसो॒ नॄन् । दि॒वस्पु॒त्रा अङ्गि॑रसो भवे॒माद्रिं॑ रुजेम ध॒निनं॑ शु॒चन्त॑: ॥
अधा मातुरुषसः सप्त विप्रा जायेमहि प्रथमा वेधसो नॄन् । दिवस्पुत्रा अङ्गिरसो भवेमाद्रिं रुजेम धनिनं शुचन्तः ॥
adhā mātur uṣasaḥ sapta viprā jāyemahi prathamā vedhaso nṝn | divas putrā aṅgiraso bhavemādriṃ rujema dhaninaṃ śucantaḥ ||

English translation:

“May we seven priests first in order engender from the material drawn the worshippers of the creator (Agni); may we Aṅgirasas be the sons of heaven, and, radiant, divide the wealth-continuing mountain.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

May we, Aṅgirasas, be the sons of heaven: divasputrā aṅgiraso bhavena, or, may we, the sons of heaven be Aṅgirasas; or, bhūtimantaḥ, possessed of superior power. The Aṅgirasas are the sons of A-ditya, aṅgirasām ādityaputratvam āmnāgyate; the text is: tasya yad retaḥ prathamam udadipyata tad asau ādityo abhavat, ityupakramya ye aṅgārā asanste aṅgiraso abhavan, that which was his seed was first manifested as Āditya, thence, in succession, those which were the cinders became the Aṅgirasas; wealth-containing mountain: ādrim rujema dhaninam, may allude to the rock in which the cows were hidden; or, adri may be rendered cloud (megha), by the disruption of which rain is made to fall
