Sanskrit text [Accents, Plain, Transliterated]:

उ॒भा जि॑ग्यथु॒र्न परा॑ जयेथे॒ न परा॑ जिग्ये कत॒रश्च॒नैनो॑: । इन्द्र॑श्च विष्णो॒ यदप॑स्पृधेथां त्रे॒धा स॒हस्रं॒ वि तदै॑रयेथाम् ॥
उभा जिग्यथुर्न परा जयेथे न परा जिग्ये कतरश्चनैनोः । इन्द्रश्च विष्णो यदपस्पृधेथां त्रेधा सहस्रं वि तदैरयेथाम् ॥
ubhā jigyathur na parā jayethe na parā jigye kataraś canainoḥ | indraś ca viṣṇo yad apaspṛdhethāṃ tredhā sahasraṃ vi tad airayethām ||

English translation:

“You have both (ever) been victorious; never have been conquered; neither of you two has been vanquished; with whomsoever you have contended you have thrice conquered thousands.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Tredhā sahasram vi tad airayethām vyakramethām: the treble manner of kinds mean: the world, the vedas, and speech; lokavedavāgātmanā tridhā sthitam, being in three ways, consisting of speech, the vedas, the world;

Sahasram = amitam, unmeasured, infinite; Aitareya Brāhman.a vi.15: After Indra and Viṣṇu had overcome the asuras, Indra said to them, we will divide he universe with you; whatever Viṣṇu traverses with three steps shall be ours the rest shall be for you, to which the asuras consented. With his first step Viṣṇu traversed the three worlds; with his second he traversed, vicakrame, the vedas; and with the third he crossed over all speech: sarvasya vāco upari tṛīyam pādam prakṛptavān, so that, in fact, nothing was left for the asuras. What is sahasram? It implies infinite, or the whole, which is by combining all worlds, all vedas, all modes of speech. Taittirīya, seventh kāṇḍa is cited: sahasra = sarvam jagat, the whole world
