I have seen this "Divine Curse" work in a few moments and sometimes taking much longer but always effective. The curse provides the option for the subject to repent and offer you an apology and repayment you feel reasonable to clear their transgression. It is up to you if you accept any attempt to make up for the insult and injury to you.
Unlike "Black Magic" curses there is no bad Karma because you are only asking for God's Judgement of this person or group of people.
The last person I asked for protection from, God judged for his malice toward me with his jealousy. "What goes around comes around."
I will use the curse when I send it to you. That might be the only effort needed. You will be given the ancient verse and simple instruction how to use it so you can continue till satisfied. It's easy and always effective.
