hmmm.... I don't pay much attention to it. John Hagee talks about that a lot, stuff like make sure you give 7 times, fast for 40 days, or the 7th month of the year is very important etc. The number 7 is very important in Jewish culture, and in Revelations the number 7 is mentioned many times. I honestly don't know if numbers in the Bible had more to do with Jewish culture (like not eating with gentiles or shaving their beards) or not.
