四分律比丘含注戒本 2.369

2.369

The Buddha was in Śrāvastī. The people of the city made offerings and sacrifices for their parents and others at crossroads or in shrines. Bhikṣus who wore rag-robes and begged for alms took and ate it themselves, and the householders criticized them together. The bhikṣus reported this fault to the Buddha, who thereupon formulated this precept.
