चत्वारो मा मशर्शारस्य शिश्वस् त्रयो राज्ञ आयवसस्य जिष्णोः । रथो वाम् मित्रावरुणा दीर्घाप्साः स्यूमगभस्तिः सूरो नाद्यौत् ॥
catvāro mā maśarśārasya śiśvas trayo rājña āyavasasya jiṣṇoḥ | ratho vām mitrāvaruṇā dīrghāpsāḥ syūmagabhastiḥ sūro nādyaut ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Four youthful sons of Masarsara vex me, three, of the king, the conquering Ayavasa. Now like the Sun, O Varuna and Mitra, your car hath shone, long-shaped and reined with splendour.
Translated by Ralph T. H. Griffith (1896)
