RV 10.120.1
तद् इद् आस भुवनेषु ज्येष्ठं यतो जज्ञ उग्रस् त्वेषनृम्णः । सद्यो जज्ञानो नि रिणाति शत्रून् अनु यं विश्वे मदन्त्य् ऊमाः ॥
tad id āsa bhuvaneṣu jyeṣṭhaṃ yato jajña ugras tveṣanṛmṇaḥ | sadyo jajñāno ni riṇāti śatrūn anu yaṃ viśve madanty ūmāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
In all the worlds That was the Best and Highest whence sprang the Mighty Gods, of splendid valour. As soon as born he overcomes his foemen, be in whom all who lend him aid are joyful.
Translated by Ralph T. H. Griffith (1896)
