YV 5.4b

In that it is (offered) to Agni, and the mouth of the sacrifice is Agni, verily he places in front prosperity and the mouth of the sacrifice; in that it is (offered) to Visnu, and Visnu is the sacrifice, verily commencing the sacrifice he continues it. There is an oblation for Sarasvati, and (an offering) on twelve potsherds for Sarasvant; Sarasvati is the new moon, Sarasvant is the full moon; verily straightway he commences these (offerings), he prospers by them. That to Sarasvant is on twelve potsherds, for pairing, for generation. The sacrificial fee is a pair of kine, for prosperity. The Rsis could not see Indra face to face; Vasistha saw him face to face; he said, 'Holy lore shall I proclaim to you so that people will be propagated with thee as Purohita; therefore do thou proclaim me to the other Rsis.' To him he proclaimed these shares in the Stoma, therefore people were propagated with Vasistha as their Purohita; therefore a Vasistha should be chosen as the Brahman priest; verily he is propagated. 'Thou art the ray; for dwelling thee! Quicken the dwelling' [1], he says; the dwelling is the gods; verily to the gods he announces the sacrifice. 'Thou art advance; for right thee! Quicken right', he says; right is men; verily to men he announces the sacrifice. 'Thou art following; for sky thee! Quicken the sky', he says; verily to these worlds he announces the sacrifice. 'Thou art a prop; for rain thee! Quicken rain', he says; verily he wins rain [2]. 'Thou art blowing forward; thou art blowing after', he says, for pairing. 'Thou art the eager; for the Vasus thee! Quicken the Vasus', he says; the Vasus are eight, the Rudras eleven, the Adityas twelve; so many are the gods; verily to them he announces the sacrifice. 'Thou art force; to the Pitrs thee! Quicken the Pitrs', he says; verily the gods and the Pitrs he connects. 'Thou art the thread; for offspring thee! Quicken offspring' [3], he says; verily the Pitrs and offspring he connects.
