Atharvaveda 3.19

Sharpened up is this incantation (? bráhman) of mine; sharpened up [my] heroism, strength; sharpened up, victorious, be the unwasting authority (kṣatrá) [of them] of whom I am the household priest (puróhita).

Up I sharpen the royalty of them, up their force, heroism, strength; I hew [off] the arms of the foes with this oblation.

Downward let them fall, let them become inferior, who shall fight against (pṛtany-) our bounteous patron (sūrí); I destroy the enemies by my incantation; I lead up our own men.

Sharper than an ax, also sharper than fire, sharper than Indra's thunderbolt—[they] of whom I am the household priest.

The weapons of them I sharpen up; their royalty having good heroes, I increase; be their authority unwasting, victorious; their intent let all the gods aid.

Let their energies (vā́jina) be excited, O bounteous one (maghávan); let the noise of the conquering heroes arise; let the noises, the clear (ketumánt) halloos, go up severally; let the divine Maruts, with Indra as their chief, go with the army.

Go forth, conquer, O men; formidable be your arms (bāhú); having sharp arrows, slay them of weak bows; having formidable weapons, having formidable arms (bāhú), [slay] the weak ones.

Being let loose, fly thou away, O volley, thou that art sharpened up by incantation; conquer the enemies; go forth; slay of them each best one; let no one soever of them yonder be released.
