YV 6.7i

All the deities were alike, and were not discriminated; these gods [2] saw these cups and drew them, Agni that for Agni, Indra that for Indra, Surya that for Surya; then indeed were they discriminated from the other gods; he, for whom knowing thus these cups are drawn, is discriminated from his evil foe. 'These worlds must be made full of light, with like strength', they say; verily with that for Agni he bestows light on this world, with that for Indra on the atmosphere, for Indra and Vayu are yoke-fellows; with that for Surya on yonder world [3] he bestows light; full of light these worlds become for him; he makes them of like strength. Bamba and Viçvavayasa found these cups, and to them these worlds, the distant and the near, became revealed; to him, for whom knowing thus these cups are drawn, these worlds, the distant and the near, become revealed. Whatever the gods did at the sacrifice the Asuras did. The gods caused the metres and the pressings to find support in the Adabhya; then the gods prospered, the Asuras were defeated; he, for whom knowing thus the Adabhya is drawn, prospers himself, his foe is defeated. Because the gods deceived the Asuras with the Adabhya (undeceivable), that is why the Adabhya has its name. He who knows thus deceives his foe; his foe deceives him not [1]. The Adabhya is the form of Prajapati, called the freer; he draws from (the Soma) which is tied up, for freedom; he who knows thus is set free from his evil foe. They kill the Soma in that they press it; in the slaying of the Soma the sacrifice is slain, with the sacrifice the sacrificer. The theologians say, 'What is it that the sacrificer does in the sacrifice whereby he goes alive to the world of heaven?' The Adabhya is the taking alive; he draws from (the Soma) before pressing; verily he makes him go alive to the world of heaven. Now they break the sacrifice asunder when they make it find support in the Adabhya; he lets go the shoots, for the continuance of the sacrifice.
