Some Pharisees and scribes came to Jesus from Jerusalem and said,
Why do your disciples break the tradition of the elders? They do not wash (their) hands when they eat a meal.
He summoned the crowd and said to them, "Hear and understand.
It is not what enters one's mouth that defiles that person; but what comes out of the mouth is what defiles one."
Then his disciples approached and said to him, "Do you know that the Pharisees took offense when they heard what you said?"
He said in reply, "Every plant that my heavenly Father has not planted will be uprooted.
Let them alone; they are blind guides (of the blind). If a blind person leads a blind person, both will fall into a pit."
