FIRST KHANDHAKA(THE FORMATION OF THE ORDER OF BHIKKHUS)
Chapter-66 : Non-Ordination & Expulsion of Those who Killed Enlightened Arhats.
1. At that time a number of Bhikkhus(Monks) were travelling on the road from Saketa to Savatthi. On the road robbers broke forth, robbed some of the Bhikkhus, and killed some of them. Then royal soldiers came from Savatthi and caught some of the robbers; others of them escaped. Those who had escaped, received pabbajja with the Bhikkhus; those who had been caught, were led to death.
2. Then those who had been ordained, saw those robbers who were being led to death; seeing them they said: 'It is well that we have escaped; had we been caught, we should also be killed thus.' The Bhikkhus said to them: 'Why, what have you done, friends?' Then those (robbers) who had been ordained, told the whole matter to the Bhikkhus. The Bhikkhus told this thing to the Lord Buddha.
'Those Bhikkhus, O Bhikkhus(Monks), were Arahats. Let a person, O Bhikkhus(Monks), that has murdered an Arahat, if this person has not received the upasampada ordination, not receive it; if he has received it, let him be expelled (from the fraternity).'
