Jaiminīya (Talavakāra) Brāhmaṇa 2.266

2.266

Now, when, though the third pressing is in the Jagatī, he proceeds with it in the Gāyatrī alone, he causes the Brahmin to share in the Vaiśya's own [property].
He wishes to give to him through faith, through work, through service.
Indeed, when faith finds a Vaiśya, then indeed he desires a Brahmin.
He gives to him.
To that very [rite] the Anuṣṭubh is appended.
Now, when he sings the Anuṣṭubh—the Śūdra belongs to the Anuṣṭubh—he causes the Brahmin to share in the Śūdra's own [property].
He wishes to give to him through faith, through work, through service.
Indeed, when faith finds a Śūdra, then indeed he desires a Brahmin.
He gives to him.
He makes his own [property] exclusive; he has a share in dominion, he has a share in the peasantry.
He attains the intermediate state; he is not defeated in the intermediate state.
A hundred attendants, or even more, attend upon him who, knowing thus, does not sing the yokes variously.
If he should sing them variously, knowing that [former teaching], let him sing them variously.
And if he should not sing them variously, knowing this [latter teaching], let him not sing them variously.
'It is misfortune for him who knows only one or the other,' said Śāṭyāyani.
