"For non-Jews, the most familiar Name derived from the Hebrew Bible is probably Jehovah, a mistransliteration of the four-letter Name, Yud-Hay-Vav-Hay, the Tetragrammaton or, in Hebrew, the Shem Hameforash. This Name is actually never vocalized in Hebrew—it is too sacred, too powerful. ... The Tetragrammaton is frequently shortened to Yah (Yud-Hey), Yahu or Yeho (Yod-Heh-Vav), especially when used in combination within names or phrases, as in Yehoshua (Joshua, meaning "the Lord is my Salvation"), Eliyahu (Elijah, meaning "my God is the Lord"), and Halleluyah ("praise the Lord")."
