四分律刪補隨機羯磨 2.151

2.151

（若二人共住，亦准此。若犯罪者，向清淨者發露，若懺悔已，方得加法。若有罪不發露者，不應清淨法也。）

(If two persons live together, it also follows this. If one has committed an offense, he reveals it to the pure one, and only after confessing can the rite be performed. If one who has an offense does not reveal it, the rite of purity is not appropriate.)
