Those who disregard all the educated evidence that Jehovah is an accurate pronunciation of God’s name come up with all sorts of specious and illogical claims. This question repeats one such ridiculous argument against the pronunciation of Jehovah.
The claim that Jehovah is linked to the Hebrew words for “Ruin” and “mischief” (HVH, St.#1943) is blatantly absurd. This claim is only something that could be spread or believed by someone with little or no knowledge of Hebrew.
The only thing “misleading” and “fake” is this question’s argument about Hebrew roots. The root from which Jehovah (or Yahweh) is derived is not Hovah but Hava, as even Strong's will tell you (#1961). No respected scholar would say otherwise.
To show how ludicrous this claim is, I’ll quote a friend who responded to this many years ago: “Many words look or sound alike, but that does not mean that they are based on the same root. For example: You can take your friend TO the store and buy TWO candy bars so that he can have one TOO. Or, a MAN can buy a MANual that clearly MANifests how to assemble something. Are the aMENdments to the constitution male in gender? Is a trinitARIAN a group of three ARIANS? Well, neither is jeHOVAH based on the root HOVAH.”
Actually, the same misleading logic and ridiculous ignorance of language is resorted by some who hate the name JESUS. They claim that “Jesus” is a corrupted form of the Messiah’s name. They claim that the name YAHU'SHUAH. YEHOSHUA was gradually changed to the pronunciation "Je-Zeus” which “misleads” us to praise the false God Zeus. They assert that abbreviation Y'Shuah became "Y'Zeus" or Je-Zeus - which became 'Jesus' in English.
Now, it is obvious to any thinking person that this kind of reasoning is bizarre and contains so many fatal logical errors that it would only convince the most gullible person. Yet, it is doing exactly what the proponents of the HOVA/Jehovah argument do. It takes a similar sound and spelling in one language and compares it to the similar sound in another language, and based on this uneducated assumption they claim that the two words are related. But, any scholar would scoff at such a perverted logic and anyone even slightly educated in language would discount it as preposterous! (It is even somewhat embarrassing to be taking the time to respond to such an unreasoning argument.)
Pronunciation-based arguments, like the “HOVAH” allegation simply do not hold water.
Any link of HAYA to HOVAH is purely a fallacious fabrication and coincidence of language which has no bearing on the correct pronunciation of God’s Name. This argument is simply a misleading and desperate attempt to diminish the solid evidence that the pronunciation Yehovah/Jehovah is a perfectly valid and accurate translation of the Divine Name.
Part of this question requires that we even be ignorant of the “Lord’s Prayer.” Yes, Jesus addressed God as “Father,” yet in the very same breath Jesus was praying that the Father’s NAME be held sacred or holy!! Yet, we are expected to believe that we can ignore that NAME? Unreal.
It was manifestly Christ's determination to make Jehovah's name known to Christian (Jn. 17:6, 26 (Cf. Jn. 12:28; 17:4, 26; Rev. 1:5).
Jesus and the Apostles also prayed to Jehovah (Mat. 6:9,), baptized in the Name of Jehovah (Mat. 29:19), did works in the Father's Name (Jn 10:25), came in the Name of Jehovah (Jn. 5:43), glorified the name Jehovah (Jn. 12:28) & etc.
Those who would be saved must "call on the name of Jehovah" (Ac. 2:21, Rom. 10:13; quoting O.T.). They must have the "name of Jehovah, *Jesus' GOD*, written on their foreheads" (Rev. 3:12) as well as the names Jehovah and Jesus together (Rev. 14:1). They must "name the Name of Jehovah" (2Tim. 2:19; quoting O.T.) and they will "know Jehovah" (Heb. 8:10,11; quoting O.T.). In these scriptures we could not replace the name Jesus with Lord and still have the same mental association and recognition of Jesus' authority. The same is true with the "name of God," people must mentally see the name Jehovah to have the proper understanding of the person being spoken of.
As Christians we cannot ignore the name of Jesus nor can we ignore the name of Jehovah (Rev.14:1). They both are essential, one as the Almighty God and one as the "mediator" "through whom all things are" (1Tim 2:5, 1Cor. 8:6, etc.). To my knowledge, only Jehovah's Witnesses meet both requirements.
In the end times True Christians would be associated with the Father's Name (Acts 15:14; Amos 9:11, 12). Refusal to use some proper form of that Name would therefore be a denial of being truly Christian.
Hope that helps,
