Um, what?
This is speaking of Jesus not the anti-christ. Jesus confirmed the covenant with the Jews for 3.5 years and was cut off in the middle of it.The overspreading of the abomination was the continuation of the daily sacrifice by the Jews. God gave them 40 years to repent and in ad 70 God destroyed the Temple and the daily sacrifices. You will not find any where in the bible that says that there will be 7 years of tribulation. Revelation speaks of a 3.5 year period. the tribulation is only 3.5 years.
