Psalms 34:21 - Joseph Benson’s Commentary on the Old and New Testaments

Evil shall slay the wicked Either, 1st, The evil of sin: his own wickedness, though designed against others, shall destroy himself. Or, 2d, The evil of misery. While the afflictions of good men shall have a happy issue, theirs shall end in their total and final destruction. They that hate the righteous shall be desolate That persecute them and plot their ruin, which is an evidence they hate them, whatsoever they may pretend to the contrary. Dr. Kennicott translates this latter clause, The haters of the Just One, Jehovah shall make desolate; a prediction awfully fulfilled in the punishment of the persecutors of the Messiah, one of whose proper titles this was, Acts 3:14.
