In addition to the number 9*42 (144) and the age of Sarah, 127 years, we have the numbers in
13! + 2882 = (288*274)2
where 274 is twice the age of Yishmael, and 288 is twice the number 144. Again the number 144, in addition to 5708 + 144 = 5501 + 27*13. There is one age that is not reported by P, the age of Esav. It should be clear, the age of Esav is 144.
Note that the above equation is mathematical, technological, in nature, and the same is true for the number 127. No way, that the numbers 127, 137, and 144 were known to special in the days of P. Hence it is prophecy. But if one would still want to deny that it is a prophecy, we will now address a truly remarkable structure of P, a structure that should settle the case.
