Mark 7:20-23 (NLT) 20 And then he added, ‘It is what comes from inside that defiles you. 21 For from within, out of a person’s heart, come evil thoughts, sexual immorality, theft, murder, 22 adultery, greed, wickedness, deceit, lustful desires, envy, slander, pride, and foolishness. 23 All these vile things come from within; they are what defile you.’

Proverbs 6:16 - 19 (KJV)

These six things doth the LORD hate: yea, seven are an abomination unto him:

A proud look, a lying tongue, and hands that shed innocent blood

An heart that deviseth wicked imaginations, feet that be swift in running to mischief

A false witness that speaketh lies, and he that soweth discord among brethren
