You are not defiled by what you eat; you are defiled by what you say and do."
References for Matthew 15:11
Then the disciples came to him and asked, "Do you realize you offended the Pharisees by what you just said?"
Jesus replied, "Every plant not planted by my heavenly Father will be rooted up,
so ignore them. They are blind guides leading the blind, and if one blind person guides another, they will both fall into a ditch."
Then Peter asked Jesus, "Explain what you meant when you said people aren't defiled by what they eat."
"Don't you understand?" Jesus asked him.
"Anything you eat passes through the stomach and then goes out of the body.
But evil words come from an evil heart and defile the person who says them.
For from the heart come evil thoughts, murder, adultery, all other sexual immorality, theft, lying, and slander.
These are what defile you. Eating with unwashed hands could never defile you and make you unacceptable to God!"
Jesus then left Galilee and went north to the region of Tyre and Sidon.
