Yochanan 15:1-8

I am HaGefen HaAmittit (the true vine) and HaAv of me is the Korem (vineyard proprietor). Every sarig (shoot, branch) in me not bearing p'ri He takes it away, and every sarig bearing p'ri He prunes that it may bear much p'ri. You are already metoharim (clean) because of the dvar which I have spoken to you. Remain in me and I in you. As the sarig is not able to bear p'ri from itself, unless it remains on the gefen (vine), so neither are you, unless you remain in me. Ani Hu (I am) HaGefen; you are the sarigim (branches). The one remaining in me and I in him, this one bears much p'ri, because apart from me you are not able to do anything. Unless someone remains in me, he is cast out as the sarig and is dried up and they gather them, and into the Eish they throw them, and they are burned. If you remain in me and the devarim of me remain in you, whatever you want, ask, and it will be done for you! By this HaAv of me was given kavod, that much p'ri you bear, and so be my talmidim.
