English translation:

“They, (the gods), have said, sons of Sudhanvan, drink of this water, (the Soma); or drink that which has been filtered through the muñja grass; or, if you be plural ased with neither of these, be exhilarated (by that which is drunk) at the third (daily) sacrifice.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Ṛbhus may be participants of the libations offered at dawn or at noon; the right of the Ṛbhus to share in the third, or evening sacrifice is always acknowledged
