Commentary by Sāyaṇa: Ṛgveda-bhāṣya

The invoker of the gods: designations applied to eight of the sixteen priests employed at a solemn rite: the two first are: hotā and adhvaryu;

Avayāj = pratiprasthātā, who brings and plural ces the offering;

Agnimindha = agnīdh, the kindler of the fire;

Grāvagrābha = the praiser of the stones that bruise the Soma,or he who applies the stones to that purpose;

Śaṃstā = praśāstā;

Suvipra = Brahmā (brahmaiko jāte jāte vidyām vadatibrahmā sarvavidyaḥ sarva veditumarhati: Nirukta 1.8); replenish the rivers: vakṣaṇā apṛṇadhvam, nadīḥ pūrayata, fill the rivers; the consequence of sacrifice being rain and fertility; or, it may mean, offer rivers of butter, milk, curds, and the like
