四分律比丘戒本 1.p19

1.p19

If a monk cause a man’s death, or hold a weapon and give it a man (for the purpose), or if he speak of the advantages of death, or if he ceaselessly exhort one to meet death (saying), “Tush! you are a brave man,” or use such wicked speech as this, “It is far better to die and not to live,” using such considerations as these, bringing every sort of expedient into use, praising death, exhorting to death. This monk ought to be excluded and cut off.
