'Rejoice, ye prosperous!' for cattle are prosperous: therefore he says, 'Rejoice ye prosperous.' 'O Lord of prayer, preserve our goods!' The Lord of prayer, forsooth, is the Brahman; and goods mean cattle: those, which did not submit, the gods on that occasion enclosed with the Brahman on the farther side, and they did not pass over it. And in like manner does he now enclose them with the Brahman on the farther side, and they do not pass over it: therefore he says, 'O Lord of prayer, preserve our goods!' Having made a noose he throws it over (the victim). Now then as to the binding itself.
