Why is the name Jehovah not used more in the Book of Mormon? In Jewish history around 150 years before Christ came Jews began taking the name Jehovah out of the Bible. In the book of Mormon, the record of the bible is on brass plates claimed from Laban 600 BC. Why is it that in the 600 BC version the name Jehovah only appears once when quoting the Bible, when in the old testament manuscripts it appears over 7,000 times? My question is relating mainly to when books of the old testament are quoted in the Book of Mormon. Mostly in 2 Nephi.
It's pretty simple. The Book of Mormon translation follows in the KJV tradition, which in turn follows in the Jewish tradition.
(1) Out of reverence, Jews never pronounced יהוה when reading scripture.

The original pronunciation of this name has possibly been lost, as the Jews, in reading, never mentioned it but substituted one of the other names of God, usually Adonai.

(Thus &quot;Jehovah&quot; is actually just a modern day guess at a transliteration of the Hebrew יהוה.)
(2) The King James Version did something similar. It was partly out of a similar tradition of reverence, and partly because they could't really write Jhvh, and they didn't want to guess at a transliteration. So in the KJV, you will find יהוה rendered as LORD or GOD.

For the LORD GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed.
Isaiah 50:7

(3) The Book of Mormon (or, more properly, the English translation of the Book of Mormon) did the same thing: יהוה  becomes Lord or God.

For the Lord God will help me, therefore shall I not be confounded. Therefore have I set my face like a flint, and I know that I shall not be ashamed.
2 Nephi 7:7

In fact, almost anytime Lord appears in the KJV Bible (or in the Book of Mormon), it is a translation for יהוה.

In the LDS faith, there's no need to avoid pronouncing or writing Jehovah (or Jahveh, Yahveh, etc.). Jehovah is regularly used, particularly when referring to Jesus before his mortal birth. The reason that it appears this way in scripture is just a custom with an interesting history.
