I could go on for pages in reply to Mr Francis Riley's assertion that there are 2 different sets of 42 month periods in the Book of Revelation. I embarked on a lot of research and then decided that simplicity was the best way to go. The beast in Revelation 13:5 is given authority for 42 months. Period. No more, no less. This beast is not being given permission to continue for ANOTHER 42 months after killing the two witnesses.
Please read the different translations in the link. I have also linked Revelation 11 for your perusal. So, the answer is No, Mr Riley. I will not accept your insights "whether I like it or not".Revelation 13:5 The beast was given a mouth to speak arrogant and blasphemous words, and authority to act for 42 months.
