A False Name for God
Jehovah's Witnesses place enormous importance on calling God by the Name 'Jehovah' Hence their very name. They say that unless God is addressed as 'Jehovah' He will not respond. As this section shows God never ever gave Himself that name. It is a relatively recent corruption. (this section will be a shock to many Christians also!)
JEHOVAH -"False reading of Hebrew YAHWEH." - WEBSTER'S COLLEGIATE DICTIONARY
JEHOVAH -"Intended as a transliteration of Hebrew YAHWEH, the vowel points of Hebrew ADHONAY (my lord) being erroneously substituted for those of YAHWEH,' from the fact that in some Hebrew manuscripts the vowel points of ADHONAY (used as a euphemism for YAHWEH) were written under the consonants YHWH of YAHWEH to indicate that ADHONAY was to be substituted in oral reading for YAHWEH. Jehovah is a Christian transliteration of the tetragrammaton long assumed by many Christians to be the authentic reproduction of the Hebrew sacred name for God but now recognised to be a late hybrid form never used by the Jews."

YHWH - "When Christian scholars of Europe first began to study Hebrew, they did not understand what this really meant, and they introduced the hybrid name "Jehovah" . . . THE TRUE PRONUNCIATION OF THE NAME YHWH WAS NEVER LOST. Several early Greek writers of the Christian church testify that the name was pronounced "YAHWEH". This is confirmed, at least for the vowel of the first syllable of the name, by the shorter form yah,which is sometimes used in poetry (e.g. Ex. 15:2) ... The personal name of God of Israel is written in the Hebrew Bible with the four consonants YHWH and is referred to as the "Tetragrammaton." At least until the destruction of the First Temple in 586 B.C.E. this name was regularly pronounced with its proper vowels, as is clear from the Lachish Letters, written shortly before that date." - ENCYCLOPAEDIA JUDAICA (Jerusalem) p. 680 Vol. 7
Note: As shown above the proper Name for God is 'YAHWEH' from the letters 'YHWH' - most Bibles will explain this in their introductory pages.
