What comes out of a man is what makes him “unclean.” For from within, out of men’s hearts, come evil thoughts, sexual immorality, theft, murder, adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. All these evils come from inside and make a man “unclean.”

The Bible (14th C BC - 2nd C AD) Christian sacred scripture

Mark 7:20-23 (NIV)
