12. “Quicken him, O gods, to be unrivalled!” —he thereby says, “Quicken him, O gods, so as to be without an enemy; for great chiefdom, for great lordship!” in this there is nothing obscure;—“for man-rule!” 'for the ruling of men,' he thereby says;—“for Indra’s energy!” 'for vigour' he means to say when he says, “for Indra’s energy;”—“him, the son of such and such (a man), the son of such and such (a woman),”—whatever be his parentage, with reference to that he says this;—“of such and such a people,” that is to say, of the people whose king he is;—“this man, O ye (people), is your king, Soma is the king of us Brahmans!” He thereby causes everything here to be food for him (the king); the Brahman alone he excepts: therefore the Brahman is not to be fed upon, for he has Soma for his king.
