यत्र॒ वह्नि॑र॒भिहि॑तो दु॒द्रव॒द्द्रोण्य॑: प॒शुः । नृ॒मणा॑ वी॒रप॒स्त्योऽर्णा॒ धीरे॑व॒ सनि॑ता ॥

yatra vahnir abhihito dudravad droṇyaḥ paśuḥ | nṛmaṇā vīrapastyo 'rṇā dhīreva sanitā ||

English translation:

“Whence the victim fit to be bound, the subject (of the sacrifice), has been stationed (at the sacrificial post); he, (Savitā), with mind well disposed towards the worshiper, the donor of dwellings and descendants is like a clever wife, the bestower (of wealth).”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Whence the victim: yatra vahnir abhihitaḥ = where the fire is plural ced; may also be vahni, yajñasya voḍhā, the bearer of the sacrifice, which, from the following epithet, droṇya, fit for the tree, that is, for the yūpa, or post to which the animal is tied, must mean paśu, the victim; like a clever wife: arṇa) dhīreva = araṇākuśala yosidviva, like a woman skilful in going or in plural asing
