Actually, Chadster I looked at your link and they are saying that the English has changed, which it has even since the 60's when I grew up. They err when they say that these things are the correct words. Not really, we is jist ignorant.
"In addition, certain idioms in the original Hebrew and Greek are a little difficult to understand today."
Abraham's bosom was what the Jews would have called Paradise as a bosom is a place of nuture and safety which is what Paradise was versus Hell thus kingdom of God is not really correct.
NT:2859
kolpos (kol'-pos); apparently a primary word; the bosom; by analogy, a bay:

Adoption in Ephesians 1:5
NT:5206
huiothesia (hwee-oth-es-ee'-ah); from a presumed compound of NT:5207 and a derivative of NT:5087; the placing as a son, i.e. adoption (figuratively, Christian sonship in respect to God):
KJV - adoption (of children, of sons).

NT:5207

There is a difference between a genetic son and adopted son. Indeed, an adopted son could never be disinherited whereas a genetic son could be. Using adoption drives home Paul's point in Ephesians one about our security in Him because everything we have is in Him. Now an Arminian might like the other translation since a genetic son could be disinherited but it is not a true translation of the word.
Thus the error page you cited is in error. It is like this every time I see the MV disciples try to trash the AV or the TR.
The 1881 guys were shanghaied by a couple of heretics using obviously bogus texts and yet all that mess is considered modern scholarship when is just old heresy disguised. Alexandria was the home of Origen, a philosophical father of the JWs, who had 7 ways of salvation. Can you really trust a text coming from that area? Other manuscripts were found in a monastary in the pile to be burned. Gee, could they be the first copies of a novice scribe that were scrapped because of their errors and because the monks did not rotate their stock they remained though not the ones actually used? What about the very expensive copy that left spaces for all the "omitted" passages? Sounds like a scribe who did not want his reputation tarnished but made a copy according to the order of the paying heretic who did not like those passages.
Vaticanus? Is it odd that most of Revelation is missing since Revelation slams dunk the RCs? Older is nto necessarily better and all the so called questionable material can be found in versions, lectionaries and writings of the early fathers that are much older than the texts used by the MVs. It is chicanery and a new version of "yea hath God said" not scholarship. Wisdom of this world most assuredly but not the wisdom of God.
