5.12.1

sámiddho adyá mánuṣo duroṇé devó devā́n yajasi jātavedaḥ |
ā́ ca váha mitramahaś cikitvā́n tváṃ dūtáḥ kavír asi prácetāḥ ||1||

Kindled this day in the home of man (mánus), thou, a god, O Jātavedas, dost sacrifice to the gods; and do thou bring [them], understanding it, O thou of friendly might; thou art a forethoughtful messenger, poet.
