Interestingly a few years before the New Testament volume of the NWT was first published, the WT society published the following in a doctrinal book from 1946 (I added boldface for the last two sentences of the quote). [See http://www.strictlygenteel.co.uk/letgodbetrue/godbetrue2.html ; the quote is from page 23 of the 1946 edition of the Let God Be True book.]
"The Scriptures written before our common era were
written practically all in Hebrew, a portion in Syriac; and in those
Scriptures the alphabetic letters for God's name occur, namely, Jod He
Vau He (,
or YHWH), from the first book to the last. This name, symbolized by
these four Hebrew consonants, occurs, all together, 6,823 times* in the
Hebrew Scriptures. The Hebrew Scriptures were first translated into
Greek about 285-247 B.C.; but some time before that the Hebrews began to
leave off pronouncing the name, out of a superstitious fear of taking
it in vain. Hence whenever they read and came to the name, they
pronounced instead the word Adonai (Lord) or Elohim (God). Hence in making that first translation into Greek known as the Septuagint Version (LXX) the translators followed the Hebrew custom and translated the above substitutes for God's name into their Greek version.
4 The writers of the Greek Christian Scriptures used that Septuagint Version
and they quoted its Greek text which omitted the literal name of
Almighty God; which partly explains why the name does not occur by
itself in the Christian Greek Scriptures.

On a different topic, for those who believe in Bible's creation account, was Adam a brunette (but without a beard), was Eve a blond, and did the serpent in the garden have legs (before the fall), considering the illustration shown in a WT book called "The Truth Shall Make You Free" (the 1943 edition). See http://www.strictlygenteel.co.uk/truthfree/truthfree6.html for the illustration; for another illustration see also http://www.strictlygenteel.co.uk/truthfree/truthfree7.html . Maybe it was that book which started JWs saying that they are "in the truth".
