四分律比丘含注戒本 3.195

3.195

The Buddha was in Śrāvastī. A householder prepared an offering of food. The group of six received soup, and when the householder recognized the order to distribute soup, the bhikṣus afterward covered the soup with rice. The householder criticized them, saying: "Taking without satisfaction, like starving people—what True Dharma is this!" The bhikṣus brought up the fault, and the Buddha consequently rebuked them and formulated the precept.
