Sama Veda II.3.2.14: By men hath Indra been advanced, the Vritra-sIayer

1. By men hath Indra been advanced, the Vritra-sIayer, to joy and strength.
Him only we invoke for help in battles whether great or small be he our aid in deeds or might!

2. For, hero, thou art like a host, art giver of abundant spoil.
Strengthening e'en the feeble, thou aidest the sacrificer, thou givest great wealth to him who pours.

3. When war and battles are on foot, booty is offered to the bold.
Yoke thou thy wildly-rushing bays! Whom wilt thou slay, and whom enrich? Do thou, O Indra, make us rich!
