Actually, it will be the Image of the Beast that causes/promotes the mark of the Beast that has 10H. The lamb like beast with two horns is the USA (the false prophet) who makes fire [WMDs] come down from heaven in the sight of men.
Well the FP will be in Israel at this time. and I do not think it will be wmd's. After all it is a miraculous sign and causes people to take the mark.
In the KJV there is no "THE" Great tribulation for 3.5 years or 7.0 years.
However, there is an unspecified amount of time "of great tribulation".
Also, there is no singular man called "THE" antichrist.
All of that misunderstanding is a fabrication due to not interpreting Dan. 9:24-27 correctly. The 70th week WAS established during the ministry of Jesus while he was in mortal flesh confirming the New covenant for 3.5 years, and then in the Holy Spirit for the latter 3.5 years, he continued confirming the New covenant with the Apostles.
Quite literally, the 70th week is about Jesus, and Pentecost onward, even to this day.
Yes there is a man called antichrist- that specific title is found in 1 JOhn.
Yes there is a specified time - it is also known as the 70th week of Daniel, great tribulation, tribulation, time of Jacobs sorrow, time of darkness , tome of mourning etc.
Other titles for the antichrist are, man of lawlessness, man of sin, the beast, etc.
You have the 70th week all screwed up.
Here are the events of the 70th week:
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
Here are your mistakes.
1. Jesus cannot be the one who ratifies the covenant. the he of 27 must refer back to its nearest antecedant which is the prince to come!
Also Jesus, did not make a covenant with Israel ever while on earth. He gave His blood to seal the New covenant, but the new covenant is Jer. 31.
2. Jesus did not end the sacrifices and oblations. they continued until 70AD. If He meant the efficcy of those sacrifices, which He did end, He would have said so. He doesn't need us to edit Him.
3. The 70 weeks oare for Jews and Israel! vse24. they are desinged to finish one transgression, end sins, to make reconciliation (Jews must) bring in everlasting righteousness, to finish visions and prophecy and anoint Jesus as King. Remember God is very specific in who the 70 weeks are for! Jews!
4. you make 69 1/2 weeks literal or 487 years and then you allegorize the last three to mean 1995 years so far. that is failing exegesis, eisegesis, grammar and hermeneutics!
Sorry but you cannot bounce from literal to allegorical and reinterpret passages to fit your idea! We must fit our ideas into what Scripture says, and not what we wish it to say.
