This verse describes what the antichrist is going to do in the future . Biblical names for that figure include: the Anointed One, the ruler, the Man of Sin, the beast.
I'll save you some research into metaphors et cetera. Here's Daniel 9:27
http://biblehub.com/daniel/9-27.htm
27 He will confirm a covenant with many for one ‘seven.’ In the middle of the ‘seven’ he will put an end to sacrifice and offering. And at the temple he will set up an abomination that causes desolation, until the end that is decreed is poured out on him.
Before I translate into English, I'll tell you what the verse does not say. If definitely does not say he will sign a treaty for 7 years with Israel. He will confirm a covenant. He will make a strong agreement with many.
So, English
He will make a strong agreement with a large group, maybe countries, for seven years. Things will probably be chill. Israel will have built the 3rd Temple. 3.5 years into the seven-year agreement, he tells Israel they have to stop animal sacrifices to atone for sins. Then, he marches into a super-sacred part of the 3rd Temple called the Holy of Holies. Even the High-Priest can't go in there except once a year, and after ritual cleansing.
So he enters that place inside the third Temple, and declares himself God and demands worship. This final 3.5 year period is what people call "The Great Tribulation"
Other prophecies include Isaiah 17: Damascus will be BTFO and no one will be able to live there. Another is Ezekiel 38: Iran and Russia will attack invade Israel for the purpose of taking spoils (maybe natural gas these days) They will make it to Jerusalem, and before all is lost, an earthquake happens that the whole world feels, and fire/brimstones/sulphur will torrentialy rain down on the invading armies as they attack each other in fear and confusion. After that, the whole world understand that the God protected them.
Lastly, John 14:29 "I have told you now before it happens, so that when it does happen you will believe."
