Thanks for your additional input on the Arabic- Muslim origin of zero. I think John G misunderstood my point. I am not saying that 60606 and 666 are the same thing.  In the Antichrist verse at Rev 13:18 we are told to look for a man associated with a number series, 6 and 6 and 6, three sixes, three numbers.
 
I am saying that the two languages God choose to communicate His word through, Hebrew and Greek, and neither language recognizes zero as a number in their counting system. So there is good reason to think Zero is not a number. It is a placeholder, not a "number".
 
 Furthermore, there is no year Zero. The year count goes 1BC , followed by 1AD.  There is no year zero. Why ? Again Zero is not a number.Therefore, when we observe a series of 60606 , the Obama Zip code, we see correctly only THREE numbers, the zeros contained therein are not numbers. Or in looking at Verse 6,606 , where the name "Barack" and (spelled inversely) "Obama" is first found in scripture (Judges 4:6) , again the zero is not a number. The association is the three numbers, 666, and the names, "Barak, son of Abinoam". This is part of the puzzle of Rev 13:18 as the words there require not just counting , but "wisdom" and the ability "to calculate". I think those points especially refer to numbers like 216 (6x6x6) and 18 (6+6+6) and also the posted  mathmatical studies on this subject by John Tng here on fivedoves.
