梵網經菩薩戒本疏 5.45

5.45

七、通塞者，義准為護佛法及調伏眾生，畜應不犯；及從惡人乞得，擬壞亦未壞，無犯。反上，一切隨畜皆犯。是故菩薩見他畜，勸令毀破；若勸不得，應乞應贖；猶亦不得，應以威逼等（檢使），要當令止。

Seventh, permission and prohibition: By reasoning, keeping [them] to protect the Buddha-Dharma and to subdue sentient beings should incur no offense; also, if one begs and obtains them from evil people with the intention of destroying them, and has not yet destroyed them, there is no offense. Contrary to the above, in all cases keeping them incurs an offense. Therefore, when a bodhisattva sees others keeping them, they should exhort them to destroy them; if exhortation fails, one should beg for them or ransom them; if that still fails, one should use intimidation and the like (supervising and dispatching) and must make them stop.
