"would turn away from you." G-d does not like promiscuity- he likes modesty and holiness etc but in the word "anything" - the word "speech" is suggested. if you punctuate the word "davar" (anything) in a different way- you can arrive at the word "dibur" (speech) "He should not see anything impure among you...etc" meaning-that even through speech one can stumble upon things that are impure- and this too can remove the Divine Presence from the nation of Israel.
