Atharvaveda 19.13

Indra's two arms [are] stout, virile (vṛ́ṣan), these two wondrous successful bulls; them will I first yoke when the conjuncture (yóga) arrives—they by which was conquered the heaven (svàr) that is the Asuras'.

Swift, sharp, terrible like a bull, greatly smiting, disturber of men (carṣaṇí), roaring, unwinking, sole hero, Indra conquered a hundred armies together.

With the roaring, unwinking, conquering, invincible, immovable, bold one—with Indra thus conquer, thus overpower the fighters, O men, with the arrow-armed bull (vṛ́ṣan).

He with the arrow-armed, he with the quiver-hung, [is] controller; he, Indra with his train, brings together the fighters—[he,] conquering those brought together, soma-drinker, defiant with his arms, of formidable bow, shooting with fitted [arrows].

To be known by his strength, stout, foremost hero, powerful, vigorous (vājín), overpowering, formidable, excelling heroes, excelling warriors, conquering with power—mount, O Indra, the victorious kine-winning chariot.

Be ye excited after this formidable hero; take hold, O companions, after Indra, the troop-conqueror, kine-conqueror, thunderbolt-armed, conquering in the race, slaughtering with force.

Plunging with power into the cow-stalls, Indra, pitiless, formidable, of hundred-fold fury, immovable, overpowering fighters, invincible—let him favor our armies in the fights.

O Bṛihaspati, fly about with thy chariot, demon-slaying, forcing away our enemies; breaking up our foes, slaughtering our enemies, be thou the helper of ourselves.

Indra [be] their leader; let Bṛihaspati, the sacrificial gift, the sacrifice, soma, go in front; in the midst of the smashing conquering armies of the gods let the Maruts go.

Of Indra the bull (vṛ́ṣan), of king Varuṇa, of the Ādityas, of the Maruts, the spirit (çárdhas) [is] formidable; the noise of the great-minded, creation-stirring, conquering gods hath arisen.

Indra [is] ours when the banners meet [in conflict]; let the arrows that are ours conquer; let our heroes be superior; us, O gods, aid ye at the invocations.
