YV 4.3e

Indra had recourse to Prajapati, to him he gave these victories (offerings); he offered them; then indeed were the gods victorious over the Asuras; in that they were victorious, that is why (the offerings) are called 'victorious'. They should be offered by one engaged in conflict; verily does he win in the conflict. a Agni overlord of creatures, may he help me; Indra of powers, Yama of earth, Vayu of the atmosphere, Surya of the sky, Candramas of Naksatras, Brhaspati of holy power, Mitra of truths, Varuna of waters, the ocean of streams, food of lordships overlord, may it help me; Soma of plants, Savitr of instigations, Rudra of cattle, Tvastr of forms, Visnu of mountains, the Maruts of troops overlords, may they help me. b O ye fathers, ye grandfathers, ye further, ye nearer, ye dadas, ye granddadas, do ye here help me. c In this holy power, this worldly power, this prayer, this Purohitaship, this rite, this invocation of the gods. What the gods did at the sacrifice, the Asuras did. The gods saw these overpowering (Homas), they performed them; the rite of the gods succeeded, that of the Asuras did not succeed. If he is desirous of prospering in a rite, then should he offer them, and in that rite he prospers. In that the All-gods brought together (the materials), the Abhyatanas are connected with the All-gods; in that Prajapati bestowed the victories (Jayas), therefore the Jayas are connected with Prajapati [1]; in that they won the kingdom by the Rastrabhrts, that is why the Rastrabhrts (supporters of the kingdom) have their name. The gods overpowered the Asuras with the Abhyatanas, conquered them with the Jayas, and won the kingdom with the Rastrabhrts; in that the gods overpowered (abhyátanvata) the Asuras with the Abhyatanas, that is why the Abhyatanas have their name; in that they conquered (ájayan) them with the Jayas, that is why the Jayas have their name; in that they won the kingdom with the Rastrabhrts, that is why the Rastrabhrts have their name.
