Rig Veda 5.69: THREE spheres of light, O Varuna, three heavens, three firmaments ye…

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.

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.

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.

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.
