Sanskrit text [Accents, Plain, Transliterated]:

वायो॑ शु॒क्रो अ॑यामि ते॒ मध्वो॒ अग्रं॒ दिवि॑ष्टिषु । आ या॑हि॒ सोम॑पीतये स्पा॒र्हो दे॑व नि॒युत्व॑ता ॥
वायो शुक्रो अयामि ते मध्वो अग्रं दिविष्टिषु । आ याहि सोमपीतये स्पार्हो देव नियुत्वता ॥
vāyo śukro ayāmi te madhvo agraṃ diviṣṭiṣu | ā yāhi somapītaye spārho deva niyutvatā ||

English translation:

“Purified (by holy acts) I bring to you, Vāyu, the Soma, first (offered to you at sacrifices) that seek to gain heaven; deity, who are ever longed over, come with your Niyut steeds to drink the Soma juice.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Yajus. 27.30; purified by holy acts: śukraḥ vratacaryādinā dīpto aham, illustrious by observing vows; I bring to you the Soma, first offered: ayāmi te madhvo agram: madhvoḥ = madhum;

Ayāmi = prāpayāmi;

Agram = itarebhyaḥ pūrvam; alternative reading: may the cup (śukra graha) come to you, ayāni, āgacchatu, which is the essence of the Soma, agram sārabhūtaḥ madhunaḥ rasasya].
