sadyó jātó vy àmimīta yajñám agnír devā́nām abhavat purogā́ḥ |
asyá hótuḥ praśíṣy r̥tásya vācí svā́hākr̥taṃ havír adantu devā́ḥ ||11||

At once, when born, he determined (vi-mā) the sacrifice; Agni became foremost of the gods; at the direction of this invoker, at the voice of righteousness (ṛtá), let the gods eat the oblation made with "hail!"
