Mark 7- Vile traditional teachings proceeding out of the mouths of the Pharisees that defiled them.

Mark 7:15
there is nothing outside the man which going into him can defile him; but the things which proceed out of the man are what defile the man.
Mark 7:16
"If any man has ears to hear, let him hear."
Keeping this in context, Yeshua is not saying that man can eat rats and pig flesh. He is speaking of the handwashing rituals of Judaism. Those handwashing rituals do nothing to purify a man. It was the vile traditional teachings proceeding out of the mouths of the Pharisees that defiled them.
