Yah & HaVaH

The Tetragrammaton is YHVH.  It is a four-lettered name translated as Yahweh or Jehovah.  Well Eve is right there.  She’s the HVH havah part. So the Yah-Havah --YHVH -- is yet another plural god-name containing masculine and feminine deities.  We have a compound deity, God-and-Goddess for Elohim and for Yahweh, the most popular names for God in the Bible.  Used thousands of times.  In Samaria, what is now Tel Aviv and parts of modern Israel, the two names of the Tetragrammaton, both feminine and masculine were intertwined in Samaritan phylacteries -  the prayer ribbons Hebrews wrap around their forearms and put on their foreheads in little boxes.

This YHVH combination of four letters reminds me of the male female chromosome thing.  Males are XY and females are XX.  So you combine an XY with an XX and you get XYXX.  The result is a Y and the other three letters where the Y happens to be the lone masculine element while the other three letters are feminine.  Just like Yah and Havah.
