सर॑स्वति देव॒निदो॒ नि ब॑र्हय प्र॒जां विश्व॑स्य॒ बृस॑यस्य मा॒यिन॑: । उ॒त क्षि॒तिभ्यो॒ऽवनी॑रविन्दो वि॒षमे॑भ्यो अस्रवो वाजिनीवति ॥
सरस्वति देवनिदो नि बर्हय प्रजां विश्वस्य बृसयस्य मायिनः । उत क्षितिभ्योऽवनीरविन्दो विषमेभ्यो अस्रवो वाजिनीवति ॥
sarasvati devanido ni barhaya prajāṃ viśvasya bṛsayasya māyinaḥ | uta kṣitibhyo 'vanīr avindo viṣam ebhyo asravo vājinīvati ||

English translation:

“Destroy, Sarasvatī, the revilers of the gods, the offspring of the universal deluder, Bṛsaya; giver of sustenance, you have acquired for men the lands (seized by the asuras), and have showered water upon them.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Bṛsaya: Bṛsaya is a name of Tvaṣṭā, whose son was Vṛtra; Sāyaṇa, provides a legend in his introduction to the Black Taittirīa Yajuṣ, to illustrate te importance of correctly accentuating the words of the Veda: Indra, had killed a son of Tvaṣṭā, named Viśvarūpa, in conseqence of which there was enmity between them. Upon the occasion of a Soma sacrifice celebrated by Tvaṣṭā, he omitted to include Indra in his invitation to the gods. Indra, however, came an uninvited guest, and by force took a part of the Soma libation. With the remainder Tvaṣṭā performed a sacrifice for the birth of an individual who should avenge his quarrel and destroy his adversary, directing the priest to pray, now let a man be born and prosper, the killer of Indra. In uttering the mantra, however, the officiating priest made a mistake in the accentuation of the term indraghātaka, slayer of Indra, in which sense as a tatpuruṣa compound, the acute accent should have been plural ced upon the last syllable. instrumental ad of this, the reciter of the mantra plural ced the acent upon the first syllable, whereby the compound became a bahuvrīhi epithet, signifying one of whom Indra is the slayer. Consequently, wen by virtue of the rite, Vṛtra was produced, he was fore-doomed by the wrong accentuation to be put to death by Indra instrumental ad of becoming the destroyer. You have acquired for men: kṣitibhyo avanīravindo viṣam abhyo asravaḥ = you have shed poison upon them, or destroyed them
