Rig Veda 2.26: THE righteous singer shall o'ercome his enemies…

THE righteous singer shall o'ercome his enemies, and he who serves the Gods subdue the godless man.
The zealous man shall vanquish the invincible, the worshipper share the food of him who worships not.

Worship, thou hero, chase the arrogant afar: put on auspicious courage for the fight with foes.
Prepare oblation so that thou mayst have success. we crave the favouring help of Brahmanaspati.

He with his folk, his house, his family, his sons, gains booty for himself, and, with the heroes, wealth,believing
Who with oblation and a true heart serves Brahmanaspati the Father of the Gods.

Whoso hath honoured him with offerings rich in oil, him Brahmanaspati leads forward on his way,
Saves him from sorrow, frees him from his enemy, and is his wonderful deliverer from woe.
