Jaiminīya (Talavakāra) Brāhmaṇa 30.178

That was the lowest [element] that the gods saw in the sacrifice. They are, as it were, past it now. Therefore, they approach it again in this way for continuity. Those gods said, "If these two Atirātras are not a sacrificial session, with what shall we cover the body of Agni Vaiśvānara?" They said, "Whichever of ours are these final, unexhausted, highest secret bodies, with them let us cover [it]." "Head of heaven, navel of earth"—that is the final, unexhausted, highest secret body of heaven and earth. "Vaiśvānara, Agni born in the sacred order"—that is the final, unexhausted, highest secret body of Agni Vaiśvānara. "Vaiśvānara, Agni born in the sacred order"—that is the final, unexhausted, highest secret body of Agni Vaiśvānara. "The sage, the sovereign ruler, guest of men"—that is the final, unexhausted, highest secret body among Indra's verses containing [the word] "sovereign ruler". "As a vessel in the mouth the gods generated [him]"—that is the final, unexhausted, highest secret body of the All-Gods.

Just as one puts garments around a person who has put on a garment [and is cold], as garments having endings, exactly so does he clothe him.

Then with these final, unexhausted bodies the gods covered the body of Agni Vaiśvānara.

In the very same way, they cover [it] now.
