יהוה

These are what is called Tetragrammaton, the four letters that spell God's name.  These four letter are YHWH or JHVH, tranlating Gods name either Yahweh or Jehovah.  The SearchGodsWord.Org says Jehovah translates the existing one.  If you click on the link under "Word Origin" you get to "to be, to become" and so-forth.

Exodus 6:3 in the bible is the first time God let mankind know his name.   What a wonderful thing, to know Gods name.

In Genesis God created everything "to become" in to existence, the heavens the earth, and mankind.

Till next time love and peace to all.
