YV 4.2b

' He said, 'Three are these forms of my own that have strength; satiate them, and then shall ye overcome the Asuras.' They said, 'Name (them).' He said, 'This is that which frees from tribulation; this is that which drives away the foe; this is that which has power' [1]. They offered to Indra, the freer from tribulation, a cake on eleven potsherds, to Indra, the driver away of the foe, to Indra, the powerful. In that they offered to Indra, the freer from tribulation, thereby they were freed from tribulation; in that they offered to Indra, the driver away of foes, thereby they drove away foes; in that they offered to Indra, the powerful, thereby they bestowed power upon themselves. They offered a cake on thirty-three potsherds; the gods are thirty-three; verily Indra takes hold of them in himself, for prosperity [2]. That was the highest victory that the gods won over the Asuras. He who has foes should in conflict sacrifice with this offering; to Indra, the freer from tribulation, he should offer a cake on eleven potsherds, to Indra, the driver away of the foe, to Indra, the powerful; by tribulation is he seized whose foe is superior to him; in that he offers to Indra, the freer from tribulation, he is freed thereby from tribulation; by foes is he beset, to whom one of his equals is superior, even [3] if no foe; in that (he offers) to Indra, the driver away of the foe, he smites away thereby his foes; in that (he offers) to Indra, the powerful, he bestows thereby power upon himself; he offers a cake on thirty-three potsherds; the gods are thirty-three; verily the sacrificer takes hold of them in himself, for prosperity, Thus is the sacrifice called 'the victorious'; he who knowing thus sacrifices with this offering wins thus the highest victory over his foe.
