Rig Veda 5.69

trī rocanā varuṇa trīṃr uta dyūn trīṇi mitra dhārayatho rajāṃsi vāvṛdhānāv amatiṃ kṣatriyasyānu vrataṃ rakṣamāṇāv ajuryam

Three spheres of light, O Varuna, three heavens, three firmaments ye comprehend, O Mitra: Waxed strong, ye keep the splendour of dominion, guarding the Ordinance that lasts for ever.

irāvatīr varuṇa dhenavo vām madhumad vāṃ sindhavo mitra duhre trayas tasthur vṛṣabhāsas tisṛṇāṃ dhiṣaṇānāṃ retodhā vi dyumantaḥ

Ye, Varuna, have kine who yield refreshment; Mitra, your floods pour water full of sweetness. There stand the Three Steers, splendid in their brightness, who fill the three world-bowls with genial moisture.

prātar devīm aditiṃ johavīmi madhyandina uditā sūryasya rāye mitrāvaruṇā sarvatāteﾱe tokāya tanayāya śaṃ yoḥ

I call at dawn on Aditi the Goddess, I call at noon and when the Sun is setting. I pray, O Mitra-Varuna, for safety, for wealth and progeny, in rest and trouble.

yā dhartārā rajaso rocanasyotādityā divyā pārthivasya na vāṃ devā amṛtā ā minanti vratāni mitrāvaruṇā dhruvāṇi

Ye who uphold the region, sphere of brightness, ye who support earth's realm Divine Adityas, The Immortal Gods, O Varuna and Mitra, never impair your everlasting statutes.
