四分比丘戒本疏 2.110

2.110

第二戒、赴請會坐。有尼偏心，越次指授，若無一比丘呵云：「大姊！且止。須待比丘食竟」者，預食之人咽咽犯。

The second precept: going to an invitation and sitting in an assembly. If a bhikṣuṇī acts with partiality, directing and giving instructions out of sequence, and if not a single bhikṣu rebukes her, saying: 'Elder sister! Stop for now. You must wait until the bhikṣus have finished eating', then those who partake of the food commit an offence with each swallow.
