RV 4.42.7
विदुष् टे विश्वा भुवनानि तस्य ता प्र ब्रवीषि वरुणाय वेधः । त्वं वृत्राणि शृण्विषे जघन्वान् त्वं वृतां अरिणा इन्द्र सिन्धून् ॥
viduṣ ṭe viśvā bhuvanāni tasya tā pra bravīṣi varuṇāya vedhaḥ | tvaṃ vṛtrāṇi śṛṇviṣe jaghanvān tvaṃ vṛtāṃ ariṇā indra sindhūn ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
All beings know these deeds of thine thou tellest this unto Varuna, thou great Disposer! Thou art renowned as having slain the Vrtras. Thou madest flow the floods that were obstructed.
Translated by Ralph T. H. Griffith (1896)
