“Whoever winks maliciously” represents just what we would think. Their eyes are “their tell” and indicate that whatever they said or did can’t be trusted and “causes grief.” Hang out with them and it will cost us!
“A chattering fool” (literally “a fool of lips”) should be understood as deceptive — and probably a babbler! Either way, because of their words, he or she “comes to ruin” and we don’t want to be there as collateral damage when it happens!
Our verse is about dishonestly, demonstrated by these two characters — their eyes show it, their lips say it.
I think the message here is, first of all, be sure I’m not that person. Secondly, realize who that person is and don’t hang out with them.
Of course, sometimes, it’s not that simple. They might be in our families, on or jobs or in our churches!?!?
Under these circumstances — whether we can see their eyes or watch their lips move — just know with whom we’re dealing…and act appropriately!
