    This video is 9:42.

    3π = 9.42

    Coincidence? I think not.

    3*1*4*1*5*9*2 = 1080 ( roughly the radius of the moon in miles ), also the number used in isopsephy ( Gematria in the Greek language ) to assign a value to the phrase " The holy spirit ".

    If you locate all triple digit strings, from 111-999, in that order, and write them in columns with the locating numbers in one column, the string in the other, (111 at the 153rd position after the decimal ),then re-write them so the highest number location first ( 888 at the 4,751st position, 666 at the 2,440th position, etc ) it will split the strings 111-999 into two sets of even and odd numbers.

    Trivial ?
