Let me add my point here if I may. My opinion is this. the name, “Jehovah” is not God’s personal name and never has been, nor will it ever be. In looking into this further, I came across a book that was written by Jason Evert entitled “Answering Jehovah’s Witnesses”
We aren’t going to get into the jw issue here, just the name, “Jehovah”. Here is what he says about that in chapter 7, titled: “Is God’s name Jehovah?” on page 94-95, he says:
"numerous reference works, such as the Jewish Encyclopedia, Encyclopedia Judaica, Webster’s Encyclopedia, Encyclopedia Britainica, Universal Jewish Encyclopedia, Encyclopedia Americana, Encyclopedia International, The Interpreter’s Dictionary of the Bible, and The New Schaff-Herzog Encyclopedia, agree that the rendering “Jehovah” is erroneous and was never used by the Jews. So where does the name Jehovah come from?
James Akin explains:
When the LORD appears in Scripture, it will be in the Old Testament and is translating the Hebrew word for the name of God - YHWH, or JHVH ( biblical Hebrew has no vowels, only consonants.) Any vowels later added are not a part of the original text. The Ten Commandments forbid anyone to misuse the name of Yahweh, stating: “You shall not misuse the name of Yahweh your God, for Yahweh will not hold anyone who misuses his name guiltless” ( Ex. 20:7; cf, Deut. 5:11).
It goes on to say in same chapter on page 97, “There is absolutely no trace of that name’s being used in the oldest manuscripts.”
