Their “false witness” and “lies” is simply misinformation which will not help others think appropriately or make good decisions. In fact, it could be hurtful to them – even deadly.
But this wise saying particularly notes that it won’t go well for the ones sharing the “false witness” and “lies,” Such deliberate misrepresentation of truth will be costly – they “will not go unpunished” and “will not go free.”
Admittedly, God isn’t mentioned here. But, to be sure, He’s been listening!
I think it’s safe to say, He will insure that such actions, words and motivations will not continue without repercussions to the perpetrators.
It’s critical they learn that such choices are wrong, even hurtful. So, now the question becomes whether they learn simply and quickly or whether they want to be difficult about it!
