9.5.2.5

'Scatter thou our scorners, O Indra!'Like a terrible, creeping beast, dwelling in the mountains, hast thou come from the farthest distance: having sharpened thy pointed, piercing thunderbolt, O Indra, beat thou off the foes, and scatter the spurners!' thus with the second two (verses) relating to (Indra) Vimridh. For now the gods, having warded off the spurners, evil, performed this rite freed from evil; and in like manner does the Sacrificer now, having warded off the spurners, evil, now perform this rite freed from evil.
