And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.

Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?

These are the things which defile a man: but to eat with unwashen hands defileth not a man.
