食家強坐戒第四十三　制意者。凡在家俗人婚會。無時久坐不去。放妨彼邪心遞相逼斥。理非所宜。又復出家離穢受染之所。事須防遠。容自壞心行。外涉譏醜。故所以制　別緣有四。一是食家甄去斷婬欲家及二俱受齋不犯。二夫婦常所居屏處。三無第四人。四申手不及戶處坐便犯。此戒因迦陀夷起過。佛便制戒。

Precept 43: Forcibly sitting in a house having a meal. The intention of the promulgation is: In general, when lay people hold weddings or gatherings, sitting for a long time without leaving obstructs them and leads to mutual vexation and scolding; reasonably, this is inappropriate. Furthermore, leaving home is departing from defilement, whereas places that harbor passion must be guarded against and avoided; it easily corrupts one's own mind and conduct and incurs worldly ridicule and ugliness externally. For this reason it was promulgated. The specific conditions are four: 1. it is a dining household—excluding households abstaining from sexual desire and those where both take up the fast, in which cases there is no offense; 2. a private place where husband and wife usually dwell; 3. there is no fourth person present; 4. sitting in a place beyond arm's reach of the door constitutes the offense. This precept was promulgated because Udāyin caused an infraction, so the Buddha instituted the precept.
