Mark 7:6, 20-23

But He said to them, Excellently and truly [so that there will be no room for blame] did Isaiah prophesy of you, the pretenders and hypocrites, as it stands written: These people [constantly] honor Me with their lips, but their hearts hold off and are far distant from Me.

And He said, What comes out of a man is what makes a man unclean and renders [him] unhallowed. For from within, [that is] out of the hearts of men, come base and wicked thoughts, sexual immorality, stealing, murder, adultery, Coveting (a greedy desire to have more wealth), dangerous and destructive wickedness, deceit; unrestrained (indecent) conduct; an evil eye (envy), slander (evil speaking, malicious misrepresentation, abusiveness), pride (the sin of an uplifted heart against God and man), foolishness (folly, lack of sense, recklessness, thoughtlessness). All these evil [purposes and desires] come from within, and they make the man unclean and render him unhallowed.
