Interesting, you guys see the 70th week as being a 7 year period just as the other 69, which I agree. The problem I see is with the other 3.5 years, it seems your saying this is an indefinite period?
who do you see as being Daniels people?
We believe the second 3.5 yrs were kept open to those under the Law covenant to be selected first to be those in the new covenant, over those of the nations. We believe with the conversion of Cornelious in 36 CE, the Law covenant came to it's close, and the Israel of God (Gal 6:16) was now being gathered from people of all tribes, nations, peoples, and tongues (Rev 5:9,10) into the new covenant.
So in answer to your second question, Daniel was a Jew by birth, and his people during his life were also natural Jews, as well as proselytes who had joined with them in worshipping Jehovah. Technically it is still the same, only now Jehovah's people are made up more of people of the nations than natural Jews.
