[506] When [a bhikkhu] has refused [further food] (pavārita), and one perceives that he has refused, if one invites him by offering non-leftover (anatiritta) chewable food (khādanīya) or consumable food (bhojanīya), there is an offense of pācittiya. When he has refused, and one is in doubt, if one invites him by offering non-leftover chewable food or consumable food, there is an offense of dukkaṭa. When he has refused, and one perceives that he has not refused, if one invites him by offering non-leftover chewable food or consumable food, there is no offense.
If one brings what is allowable for a watch of the night (yāmakālika), what is allowable for seven days (sattāhakālika), or what is allowable for life (yāvajīvika) for the purpose of food, there is an offense of dukkaṭa. If at his word [the other] accepts it, thinking, "I shall chew it, I shall eat it," there is an offense of dukkaṭa. For every mouthful swallowed, there is an offense of dukkaṭa.
When he has not refused, and one perceives that he has refused, there is an offense of dukkaṭa. When he has not refused, and one is in doubt, there is an offense of dukkaṭa. When he has not refused, and one perceives that he has not refused, there is no offense.
