四分律比丘含注戒本 3.171

3.171

The Buddha was in Śrāvastī. A householder prepared an offering of food, personally serving it. After serving the rice himself, he went inside to fetch soup and returned, but the rice had already been finished; when he then gave the soup, he went back again to fetch rice, and when the rice was brought, the soup was finished. He criticized them for resembling starving people. The bhikṣus brought up the fault, and [the Buddha] consequently rebuked them and formulated the precept.
