'Destructive' in the Bible
Mighty will be his skills, but not from his own abilities. He'll be remarkably destructive, will succeed, and will do whatever he wants, destroying mighty men and the holy people.
He will make a binding covenant with many for one week, and for half of the week he will suspend both the sacrifice and grain offerings. Destructive people will cause desolation on the pinnacle until it is complete and what has been decreed is poured out on the desolator.'"
Armed forces will arise from his midst, and they'll desecrate the fortified Sanctuary, abolish the daily sacrifice, and establish the destructive desecration.
There will be 1,290 days from the time the regular burnt offering is rescinded and the destructive desolation established.
