Sanskrit text [Accents, Plain, Transliterated]:

सेने॑व सृ॒ष्टामं॑ दधा॒त्यस्तु॒र्न दि॒द्युत्त्वे॒षप्र॑तीका ॥
सेनेव सृष्टामं दधात्यस्तुर्न दिद्युत्त्वेषप्रतीका ॥
seneva sṛṣṭāmaṃ dadhāty astur na didyut tveṣapratīkā ||

English translation:

“[7-8] He terrifies (his adversaries) like an army sent (against an enemy), or like the bright-pointed shaft of an archer. Agni, as Yama, is all that is born; as Yama, all that will be born; he is the lover of maidens, the husband of wives.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Yamo ha jāto, yamo janitvam: yama is interpreted as: yacchati dadāti kāmān stotṛbhyaḥ, he who gives the desired object to the worshippers; so, Yama becomes a synonym of Agni: yam agnir ucyate; or, Agni becomes one of the twins (yama), by the simultaneous  birth of Indra and Agni (according to Yāska);

Jāta = all existing beings;

Janitva = those that will exist; the terms imply dependence of all existence, past, present, or future, upon worship with fire; lover of maids: the essential part of the nuptial ceremony is completed when the maiden offers to fire; husband of wives: An allusion to a legend; Soma obtained a maiden and gave her to gandharva, Viśvāvasu; he transferred her to Agni, who gave her to a mortal husband and bestowed upon her wealth and offspring; the reference is to the wife as a chief participant in the oblations to fire
