The Jewish people were originally not allowed to utter the name of God, only the priests, hence the term 'inutterable name' which was often used. The fact is, the name of God as translated from the tetragrammaton (which is YHVH or YHWH) has been lost. There are no vowels, the term Jehovah or Ye-ho-wah as it probably should be pronounced is one translation, as is Yahweh.
The only person allowed to utter the name of God was the high priest of the temple. He was only allowed to say the unutterable name once per year, on the day of atonement, Rosh Hashanah, when he would go behind the veil into the holy of holies to present the sacrificial blood.
Actually, to pronounce YHWH as "yahweh" or "jehovah" is entirely inaccurate because, as we have already stated, that name wasn't allowed to be pronounced. The reason we think "yahweh" or "jehovah" is the name of God is because some ignorant person long ago tried to pronounce syllables that were never meant to be pronounced in the first place.
At the end of the day, Christ never referred to God as 'Jehovah' unless quoting from the ancient scrolls. As the model of the Christian walk, he referred to God as 'Father' which is how Christians should probably refer to God. Knowing his name is important yes, but in terms of the concept of a personal relationship with God the model of Father is far more logical (do you call your dad by his name?). I don't believe the bible translators were conspirators I just believe they were reflecting the traditions of the jewish people in their translations by using a supreme and all-encompassing title to reflect the name of God.
PS - the new world translation apparently had no qualified translators on board, and didn't use any of the ancient scrolls in translation. It's a contentious translation, but I guess so is the NIV for other reasons. There are biases.
PPS - the new world translation incorrently inserts the name of Jehovah into the new testament where titles such as Lord are used. There is also an interchangeable use of the term 'Lord' about Jesus and also God the Father, and they wanted to distinguish between those even though it didn't show that in the texts. they hate this obviously because they don't believe in the trinity.
yes, Bias all around.
Christianity turns the tables on the name of God. In Christianity the name of God is not "yahweh" or "jehovah" but Jesus. This is, Jesus is the name of God. Jesus is a name we can pronounce, call upon, and have a relationship with. Jesus is God incarnate in the flesh. This is why, when the Pharisees asks Jesus about his true identity, Jesus responds with, "I AM". Jesus is God, revealed.
"Very truly I tell you," Jesus answered, "before Abraham was born, I am!" (John 8:58)
