His forces will rise up and desecrate the temple fortress. They will abolish the daily sacrifice and set up the abomination of desolation.
Daniel 11:31 In-Context
“At the appointed time he will invade the South again, but this time the outcome will be different from what it was before.
Ships of the western coastlands will oppose him, and he will lose heart. Then he will turn back and vent his fury against the holy covenant. He will return and show favor to those who forsake the holy covenant.
“His armed forces will rise up to desecrate the temple fortress and will abolish the daily sacrifice. Then they will set up the abomination that causes desolation.
With flattery he will corrupt those who have violated the covenant, but the people who know their God will firmly resist him.
“Those who are wise will instruct many, though for a time they will fall by the sword or be burned or captured or plundered.
