佛說目連問戒律中五百輕重事經 2.46

2.46

問：「為僧乞食道路，己身得食不？」答：「若去時先白僧，僧聽好。若不白，還白聽亦好。若不聽，還償。若不償，犯重。」

Question: "When begging for food on behalf of the saṃgha on the road, may one eat it oneself?"
Answer: "If, upon departure, he first announced it to the saṃgha and the saṃgha consented, it is fine. If he did not announce it, announcing it upon return and receiving consent is also fine. If they do not consent, he must repay it. If he does not repay it, he commits a grave offense."
