Sama Veda II.3.1.6: The watchful guardian of the people hath been

1. The watchful guardian of the people hath been born, Agni, the very strong, for fresh prosperity.
With oil upon his face. with high heaven-touching flame, he shineth splendidly, pure, for the Bharatas.

2. O Agni, the Angirasas discovered thee what time thou layest hidden, fleeing back from wood to wood.
Thou by attrition art produced as conquering might, and men, O Angiras, call thee the Son of Strength.

3. The men enkindle Agni in his threefold seat, ensign of sacrifice, the earliest bousehold-priest.
With Indra and the Gods together on the grass let the wise priest sit to complete the sacrifice!
