Jehovah`s witnesses are blind to the fact that the name/word "Jehovah" does not occur once ,not once in the Christian Greek text that Jehovah`s Witnesses base their New world Translation on for the new Testament.
Neither Jesus ,the Apostles ,nor any of the disciples or any body else ever uttered the name/word Jehovah in the Christian Greek Scriptures /New Testament.
And not once in the Christian Greek Scriptures are Christians admonished to witness to,for or about Jehovah ,not once.
However their are over 30 times Christians are to bear witness to,for and about Jesus Christ .
