NgokukaJohane 12:37-41

Nakuba ayezenzile izibonakaliso eziningi, bezibonela ngawabo, kodwa abakholwanga kuye, ukuze kugcwaliseke izwi lika-Isaya, umphrofethi, elithi: “Nkosi, ngubani owakholwa ngumbiko wethu na? Ingalo yeNkosi yambulelwa bani na?” Ngalokho-ke kabakwazanga ukukholwa, njengokuba u-Izaya washo futhi, wathi: “Uphuphuthekisile amehlo abo, wayenza lukhuni inhliziyo yabo, ukuze bangaboni ngamehlo abo, bangaqondi ngenhliziyo yabo, funa baphenduke, ngibaphilise.” U-Isaya wakusho lokho ngokuba ebona inkazimulo yeNkosi, futhi wakhuluma ngayo.
