YV 1.6r

He buys (it) with a she-goat; verily he buys it full of fervour; he buys (it) with gold; verily he buys it bright [1]; he buys (it) with a milch cow; verily he buys it with milk for the mixing: he buys (it) with a bull; verily he buys it with Indra; he buys (it) with a draught ox, the draught ox is the bearer; verily by the bearer he buys the bearer of the sacrifice; he buys with two as a pair, to win a pair; he buys with a garment, the garment is connected with all the gods; verily he buys it for all the gods. These,, make up ten. The Viraj has ten syllables, the Viraj is food; verily by the Viraj he wins proper food [2]. 'Thou art the bodily form of penance, Prajapati's kind', he says, verily the Adhvaryu makes atonement to the cattle, that he may not be cut off. He attains prosperity, be obtains cattle who knows thus. 'The bright with the bright for thee I buy', he says that is according to the text. The gods retook by force the gold where with they purchased the Soma, saying, 'Who shall barter brilliance?' The gold by which [3] he buys the Soma he should retake by force; verily he bestows brilliance upon himself. 'Ours be light, darkness be on the Soma seller', he says; verily he places light in the sacrificer, and bestows darkness on the Soma-seller. If he were to strike (the Soma-seller) without inter twining (the flock of wool), then the serpents would bite during that year. 'Thus do I intertwine the necks of the biting serpents', he says; the serpents do not bite that year, he pierces the Soma-seller with darkness. 'O Svana [4], Bhraja', he says; they indeed in yonder world guarded the Soma; from them they grasped the Soma; if he were not to indicate to them those that serve as the price of Soma, he would not have purchased the Soma, and they would not guard the Sonia for him in yonder world. In that he indicates to them those that serve as the price of Soma, he really purchases the Soma, and they guard the Soma for him in yonder world.
