Are you talking about the "abomination of desolation" referred to in Matthew 24:15?
“When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand”
If so, I believe this is referring to something that has already happened; the Siege of Jerusalem in 70 AD. The abomination of desolation is referring to the Roman army which was carrying golden eagle standards.
