Sanskrit text [Accents, Plain, Transliterated]:

यू॒प॒व्र॒स्का उ॒त ये यू॑पवा॒हाश्च॒षालं॒ ये अ॑श्वयू॒पाय॒ तक्ष॑ति । ये चार्व॑ते॒ पच॑नं स॒म्भर॑न्त्यु॒तो तेषा॑म॒भिगू॑र्तिर्न इन्वतु ॥
यूपव्रस्का उत ये यूपवाहाश्चषालं ये अश्वयूपाय तक्षति । ये चार्वते पचनं सम्भरन्त्युतो तेषामभिगूर्तिर्न इन्वतु ॥
yūpavraskā uta ye yūpavāhāś caṣālaṃ ye aśvayūpāya takṣati | ye cārvate pacanaṃ sambharanty uto teṣām abhigūrtir na invatu ||

English translation:

“Whether they be those who cut the (sacrificial) post, or those who bear the post, or those who fasten the rings on the top of the post, to which the horse (is bound); or those who prepare the vessels in which the food of the horse is dressed; let the exertions of them all fulfil our expectation.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

The post: twenty-one posts, of different kinds of wood, each twenty-one cubits long, are to be set up, to which the different animals are to be fastened, amounting to three hundred and forty-nine, besides two hundred and sixty wild animals, making a total of six hundred and nine (Kātyāyana); the text seems to refer to a single post: caṣālam ye aśvayūpāya takṣati: caṣāla = a wooden ring, or bracelet, on the top of the sacrificial post; or, it was perhaps a metal ring at the foot of the post
