The Factor?

It is advertised as "The Spin Stops Here".  Rightly so; still in all, credit should be given where credit is due.  On commenting from Glenn Beck's book, "The Overton Window", both, Beck and O'Reilly make it a point to inform all that a quote from the book, "a dog will return to it's own vomit", is from Rudyard Kipling.  True it is.  But didn't Kipling get it from Proverbs 26:11 and or 1 Peter 2:22?  They were both written more than a couple, plus or minus, thousand years and change before Kipling.  Look it up!
