30 'Allow both to grow together until the harvest; and in the time of the harvest I will say to the reapers, "First gather up the tares and bind them in bundles to burn them up; but gather the wheat into my barn."' "
14 "Let them alone; they are blind guides of the blind. And if a blind man guides a blind man, both will fall into a pit."
