Summary: David summarizes the wicked, people who lie and steal for their own benefit. He knows the fate awaiting them includes God taking all that was ill-gotten. By contrast, the wise put their trust in God to be kind and also just in His judgement.
Response: It's becoming more and more clear that God has to prune. Not every ministry started has to continue indefinitely, and few really can without being corrupted or twisted. Not every tongue can be counted on to stay true with its message. I pray I have the patience to seek God's discernment as, to be honest, I have a big change coming up soon in my life.
