Markos 7:20-23

And Rebbe, Melech HaMoshiach was saying, It is the thing proceeding out of the ben Adam that makes him tameh. For from within the lev of the ben Adam comes evil cravings and machshavot: then zenunim (fornications), gneyvot (thefts), retzichot (murders), Niufim (adulteries), chamdanut (greediness), rishah (wickedness), nechalim (scheming deceitfulness), zimmah (lewdness, sensuality), an ayin horo or roah ayin (an envious evil eye), lashon hora, gaavah (pride), and ivvelet (foolishness). All these evil things proceed from within and make the ben Adam tameh.
