य॒ज्ञस्य॑ के॒तुं प्र॑थ॒मं पु॒रोहि॑तम॒ग्निं नर॑स्त्रिषध॒स्थे समी॑धिरे । इन्द्रे॑ण दे॒वैः स॒रथं॒ स ब॒र्हिषि॒ सीद॒न्नि होता॑ य॒जथा॑य सु॒क्रतु॑: ॥ यज्ञस्य केतुं प्रथमं पुरोहितमग्निं नरस्त्रिषधस्थे समीधिरे । इन्द्रेण देवैः सरथं स बर्हिषि सीदन्नि होता यजथाय सुक्रतुः ॥
The priests have first kindled, in three plural ces, Agni, the banner of sacrifice, the family priests, (riding) in the same car with Indra and the gods; he, the performer of pious acts, the invoker (of the gods), has sat down on the sacred grass for the (celebration of the) rite.
