四分律比丘含注戒本 1.522

1.522

The Buddha was in Śrāvastī. The group of six [monks] kept bowls; setting aside inferior ones, they constantly sought fine bowls, and ended up keeping a great many. Householders wandering and sightseeing then criticized them, saying that they were no different from a potter's earthenware shop. The bhikṣus reported the fault, the Buddha then rebuked them, and laid down this precept.
