Kaushitakagrihyasutra 3.12: atha dvādaśaḥ khaṇḍaḥ

For twenty-six reasons, indeed, sir, or for an unlimited number, should a Brahmin study [the Veda].

Namely: he is born of a noble family,

he is capable,

his ancestors were worthy,

this is practiced by the virtuous,

this is a debt of a Brahmin,

and Vedic study is the most auspicious of rites.

And [thinking]: 'Having studied, I shall know what is to be done and what is not to be done.'

And the learned are honored everywhere.

"And students attend [upon me];

and they honour [me] everywhere;

I shall have access everywhere;

I shall sacrifice;

I shall officiate at sacrifices;

I shall be distinguished;

and I shall enjoy well-prepared oblations;

and through me, endowed with daily Vedic recitation, my parents will thrive in happiness in the heavenly world;

and through student-chastity I shall become long-lived and glorious;

and through daily Vedic recitation I shall swiftly destroy evil."

All worlds belong to one endowed with daily Vedic recitation.

Nothing is unobtainable for him.

There is no return for him.

The word 'Veda' applies to both Mantra and Brāhmaṇa.

For the Veda is the root of dharma.

And sacred knowledge cannot be stolen by thieves.

And each single verse, when properly recited, becomes a wish-yielding cow.

Whatever sacrifice one recites, by that very one an offering has been made.

Regarding this, there are also verses:

"Conspicuous, agile, skillful, friendly, resolute, pure, / virtuous, learned, self-controlled, he indeed purifies the company.

Accumulators always fear thieves, the king, fire, and water; / but the learned, free from anxiety, live in comfort with inexhaustible livelihoods.

This is the complete statement concerning the purpose of Vedic knowledge: / being truthful and self-controlled, one should make an effort in study."

Regarding this, the Ṛṣi also says:

"Him who is awake the verses desire; him who is awake the Sāman chants approach; to him who is awake this Soma says: 'I am yours, resting in your friendship.'"
