Matthew 15:9 Meaning

7Ye hypocrites, well did Esaias prophesy of you, saying,

8This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.

9But in vain they do worship me, teaching for doctrines the commandments of men.

10And he called the multitude, and said unto them, Hear, and understand:

11Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
