Jaiminīya (Talavakāra) Brāhmaṇa 1.177

'I would praise the dear friend now, the grandson of strength, for he has life'— / If he should say: 'he does not have life', the sacrificer would not have life. / But when he says: 'for he has life', the Udgātṛ bestows life in himself and in the sacrificer. / 'hiṃ māyāsmāyūḥ, may we enjoy the gifts of the offering'— / If he should say: 'dāśema' ('may we serve'), they would be wanderers away from him. / But when he says: 'āśemā' ('may we enjoy'), he simply enjoys. / 'May we enjoy the gifts of the offering; may he be a helper in contests; may he grow in our favor'— / for the sacrifice is as if grown old at this time. / 'And the protector of many'— / If he should say: 'of thin ones' (tanūnām), the sacrificer would be as if thin. / But when he says: 'of many' (bahūnām), he thereby makes him the protector of many.

Regarding this they say: 'The verses of the Yajñāyajñīya are deficient by one syllable.'

That is an opening in the sacrifice.

When the Udgātṛ singing it does not cover it up, he makes an opening in the Yajñāyajñīya.

Through the opening of the Yajñāyajñīya the sacrifice leaks; following the sacrifice, the sacrificer; following the sacrificer, the offspring.

In it he should place speech.

Speech is the brahman.

'And speech, protector of many'—

Some place 'gauḥ' ('cow'), saying: 'The cow is all food, for the securing of all food.'
