Commentaries:
"Wicked" renders into English the Greek poneros, an adjective that denotes an active, malignant kind of evil. It refers to what is not only ugly and useless, but to what is injurious and destructive. Like a cancer to the human race, Satan is aggressively engaged in destruction and causing pain, injury, and death.
