Mysteries of "Mene Mene"

Mysterious words written written on the wall by the angel in Daniel 5:25 - "MENE MENE TEKEL UPHARSIN".  Based on Daniel's interpretation of the dream in Chapter 5, there's no apparent reason for the double loshon of MENE (Daniel only interprets the word once).  The gematria of the entire phrase is 1118.  A tanach search finds 3 phrases within one perek of each other in lech lecha with a gematria of 1118, each with double loshonot: "yada tada" (15:13), "harbeh arbeh" (16:10) and "be'er be'er" (16:14).  The "yada tada" has 2 separate sequential combinations of 1118 within the same pasuk. 

Also, the only other time in tanach the word "TEKEL" is used is within these perakim - Breishis 16:4. 

The gematria of MENE is 91 - same as A-d-o-n-a-i Yud-Hay-Vav-Hay.

All of these pesukim in Breishis are either in the story of the Bris Bein HaBesarim or the expulsion of Hagar.
