Here now some clean them with the formula: 'For the gods get clean! for the gods get clean!' But let him not do so: for this oblation is intended for some particular deity; and if he were to say, 'For the gods get clean!' he would make it one intended for all the deities, and would thereby raise a quarrel among the deities. Let him therefore do the cleaning silently!
