ماجهيما نيكايا 3:35
SUJATOSanti, bhikkhave, bhikkhū imasmiṁ bhikkhusaṅghe tiṇṇaṁ saṁyojanānaṁ parikkhayā sotāpannā avinipātadhammā niyatā sambodhiparāyanā—
In this Saṅgha there are mendicants who, with the ending of three fetters are stream-enterers, not liable to be reborn in the underworld, destined for awakening.
