Musar zu Tehillim 83:4

And likewise the group of destroyers of the vineyard of the Lord - such as those that cause the masses to sin - are haters of the Lord. As you would say that people that destroy the cities of the king or his vineyards and orchards are haters of the king. And it is stated (Isaiah 5:7), “For the vineyard of the Lord of Hosts Is the House of Israel, and the seedlings he lovingly tended are the men of Judah.” And it is stated (Psalms 83:4), “They plot craftily against Your people, take counsel against Your treasured ones.” And it is stated (Psalms 83:6), “Unanimous in their counsel they have made an alliance against You.” And it is stated (Psalms 2:2), “and regents intrigue together against the Lord and against His anointed.” Therefore our Rabbis, may their memory be blessed, said (Rosh Hashanah 17a) that those that sinned and cause the masses to sin descend to Gehinnom, and are judged there for generations and generations.
