大比丘三千威儀 2.91

2.91

There are further five matters: first, when a sthavira expounds the scriptures, one must not correct him from below. Second, if sthaviras dispute among themselves, one must not assist either from below. Third, when junior monks dispute among themselves or make a report, one must not forcibly rebuke and stop them. Fourth, when the vihārapāla comes forward with a report sending someone on an errand, a sthavira should immediately rise, step down from the seat, and say, 'Yes.' Fifth, one must not say: 'It is sthavira so-and-so's turn to go; junior monk so-and-so is constantly being assigned, but earlier I did such-and-such myself.'
