四分律比丘含注戒本 3.18

3.18

是中有比丘尼指示「與某甲羹，與某甲飯」，是比丘應語彼比丘尼如是言：「大姊且止，須諸比丘食竟。」若無一比丘語彼比丘尼言「大姊且止，須諸比丘食竟」者，是比丘應向餘比丘悔過言：「大德！我犯可訶法，所不應為，我今向大德悔過！」是名悔過法。

and there is a bhikṣuṇī giving directions: "Give soup to so-and-so, give rice to so-and-so," that bhikṣu ought to speak to that bhikṣuṇī, saying: "Elder sister, wait a moment; wait until all the bhikṣus have finished eating." If not a single bhikṣu says to that bhikṣuṇī: "Elder sister, wait a moment; wait until all the bhikṣus have finished eating," that bhikṣu ought to confess to the other bhikṣus, saying: "Venerable sir! I have committed a blameworthy dharma, which ought not to be done. I now confess to the venerable sir!" This is called a confessable dharma.
