Hello Dear John B,
 
Well, firstly what a comprehensive amount of points you came up with and i write with Thanks for that! You have certainly made me ponder and whole new lot of circumstances, i had forgotten about the dry bones, although that could be the nation of Israel also?
 
After thinking about what you have said i still am convinced that these Four Angels from Rev. 7:1 are staying, put because after the pole shift there would otherwise be catastrophic loss of life and the population of the world would be vastly reduced? and the whole of Revelation deals with ways of reducing mankind through His Judgments? but in G-d's specific ways for instance, the Four Horsemen of the apocolypse are given ways of reducing the populace but only when they are released is the killing begun? the same with the rest of the seals and then the Trumpet Judgments?
 
Also! i have a strong feeling that the Angels at the river Euphrates are specific to that area and are not the same foour as in Rev 7:1 ? In the Book of Enoch these angels are spoken of as at Euphrates? i have no clue what chapter, i will spend today going through it! my copy of Revelation is full of highter pen and i understand what i have learned but when i just looked at my copy of the Book of Enoch, it has none! so i am at a loss to which but it is, but i will attend to that and let you know, i just wanted to answer your kind response....
 
Well, anyway, there are so many milllions of angels and the ones in the Book of Enoch much light is given to their end-time jobs, so thats all i know in my heart!  i'm obviously not an academic but the Holy Spirit helps me all the time!!! i send brotherly love and salutaions from UK and wait in trepidation for the olympics opening night, i heard someone say that they'll wait for all the dignitaries to go before anything occurs? like the next day? but i don't know, are "they" that bothered who's blood except their own is shed?
 
Thanks again for all your thoughts, there is surely much to mull over.....!
Maranatha.
