YHWY

Is the usual reference to the Hebrew name for God, which is spelled (in the Hebrew alphabet): י (yodh) ה (heh) ו (vav) ה (heh) or הוהי (YHWH).  It is the distinctive personal name of the God of Israel.  Of all the names of God, the one which occurs most frequently in the Hebrew Bible is the Tetragrammaton, appearing 6,823 times, according to the Jewish Encyclopedia.  The Biblia Hebraica and Biblia Hebraica Stuttgartensia texts of the Hebrew Scriptures each contain the Tetragrammaton 6,828 times.  In Judaism, the Tetragrammaton is the ineffable Name of God, and is therefore not to be read aloud.  In the reading aloud of the scripture or in prayer, it is replaced with Adonai (“My Lords”, commonly rendered as “The Lord”).  Other written forms such as י (yod) ה (heh) (YH or Yah) are in fact pronounced during prayer.
