If a monk go to the house of his patron, and be urgently invited to take cakes (dumplings), cooked rice, or ground corn (parched and then ground) the monk as he pleases (requires) may take two or three bowlfuls; then he should take it within the monastery, and divide it with the other monks; if a monk, except in case of sickness, take more than two or three bowlfuls, it is pācittiya.
