Some Christians, especially Jehovah's witnesses, use this name for the Heavenly Father. However, every scholar and every reference book I have ever checked on "Jehovah" (including Jehovah's witness tracts) has said that this is not the way you pronounce His name! First of all it is impossible because the fact that Hebrew language has no "J" sound! . According to the Encyclopaedia Brittanica, 1991 under the heading "Yahweh", here is how this name came into being:
"The Masoretes, who from about the 6th to the 10th century worked to reproduce the original text of the Hebrew Bible, replaced the vowels of the name YHWH with the vowel signs of the Hebrew word Adonai or Elohim. Thus the artificial name Jehovah (YeHoWaH) came into being."
So we see here one of many confirmations that the name Jehovah is not really His name at all! But it is a artificial name that was invented by man. Does man have the right to change the name of the one who created him? I think not! But that is exactly what has happened here.
Now let's look a little more deeply into this name Jehovah. Notice that many Hebrew names contain the first part of Yahweh's name which is Yah. This is true in the name Isa-YAH (Hebrew: YeshaYAH), which means "Yah is Salvation". Also in Jeremi-Yah (Hebrew: YermeYAH), Obadiah, Zechariah, and so on. Taking this knowledge, apply this to the name Je-hovah with Jeh being the first part of His name. First of all it doesn't add up when it comes to the names of these prophets. (Isaiah's name isn't IsaJEH) Second, the Hovah part of Je-hovah means RUIN and MISCHIEF in Hebrew according to Strong's Concordance #1943:
#1943 Hovah, another form for 1942; RUIN:-MISCHIEF
Is this a good description of our Creator?
No, it is blasphemy, and it is also breaking the third commandment.
