आ रोद॑सी बृह॒ती वेवि॑दाना॒: प्र रु॒द्रिया॑ जभ्रिरे य॒ज्ञिया॑सः । वि॒दन्मर्तो॑ ने॒मधि॑ता चिकि॒त्वान॒ग्निं प॒दे प॑र॒मे त॑स्थि॒वांस॑म् ॥
आ रोदसी बृहती वेविदानाः प्र रुद्रिया जभ्रिरे यज्ञियासः । विदन्मर्तो नेमधिता चिकित्वानग्निं पदे परमे तस्थिवांसम् ॥
ā rodasī bṛhatī vevidānāḥ pra rudriyā jabhrire yajñiyāsaḥ | vidan marto nemadhitā cikitvān agnim pade parame tasthivāṃsam ||

English translation:

“Those who are to be worshipped, (the gods), inquiring between the expansive heaven and earth (for Agni), recited (hymns) dedicated to Rudra; the troop of mortal (Maruts), with (Indra), the shrer of half the oblation, knowing where Agni was hiding found him in his excellent retreat.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Dedicated to Rudra: Rudra is equated with Agni; the hymns to Agni are called Rudrīya, for Rudra is Agni: rudra-agniḥ; a legend is cited: during a battle between the gods and asuras, Agni carried off the wealth which the former had concealed; detecting theft, the gods pursued the thief, and forcibly recovered their treasure; Agni wept (arodīt) at the loss; thereafter he was called Rudra (Taittirīya Saṃhitā 1.5.1.1); the text has martaḥ, the mortal; the term, marudgaṇa is added;

Nemadhitā = half-sharer, from nema, a half; Indra is entitled to all sacrifices; all the other gods get half the share: sarve devāḥ eko ardhaḥ, Indra eka evaparo ardhaḥ (Taittirīya 5.4.8.3)

Details:
