The verse: Rev. 13:8

Notice the difference between KJV & NKJV in contrast to the others...the KJ's end with the word "world" while the others end with the word "slaughtered / slain / killed".
The explanation for the difference as found in the NET note for this verse is:
The prepositional phrase "since the foundation of the world" is traditionally translated as a modifier of the immediately preceding phrase in the Greek text, "the Lamb who was killed" (so also G. B. Caird, Revelation [HNTC], 168), but it is more likely that the phrase "since the foundation of the world" modifies the verb "written" (as translated above). Confirmation of this can be found in Rev 17:8 where the phrase "written in the book of life since the foundation of the world" occurs with no ambiguity.
Hurrah for Rev. 17:8...but that is perfectly irrelevent, especially when the Greek concurs with the KJ's.
Let's look at the Greek:

Notice that the phrase in question, "from the foundation of the world", occurs exactly where KJV/NKJV presents it...after "slaughtered / slain". I realize that proximity often means next-to-nothing in Greek, but in this case, it is quite relevent. Notice that the NET note doesn't dismiss the grammatic possibility of the KJ readings, it just has determined that it, along with the other modern versions, has "deeper insight" into the text, even if it means linking together two phrases across a chasmic distance of chapters when there is a PERFECTLY DOCTRINALLY VIABLE option literally abutting the phrase in question.
I'm not here saying that Rev. 17:8 isn't viable in its own way...it certainly is. But what I am questioning is the credibility and sheer hhutspah of a textual committee (in this case, actually, many textual committees) to literally STRETCH for a distant possibility when a valid (and I think unquestionably correct one) is at hand. Before I make my case, let me assert that this isn't a Byzantine/Majority text bias-I use NASB as my preferred text...and so I am here disagreeing with it as well as the other NA/USB texts. But notice, this isn't really a Majority vs. NA issue...this is an EDITORIAL edict. For that reason I believe that this decision is also flagrantly inappropriate. But on to my evidence...
1 Pet. 117
If you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your stay on earth;
18 knowing that you were not 1redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers,
19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.
20 For He was foreknown before the foundation of the world, but has appeared 2in these last times for the sake of you
21 who through Him are believers in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God.
1 Or ransomed 2 Lit at the end of the times

Acts 2
22 “Men of Israel, listen to these words: Jesus the Nazarene, a man 1attested to you by God with 2miracles and wonders and 3signs which God performed through Him in your midst, just as you yourselves know—
23 this Man, delivered over by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of 4godless men and put Him to death.
1 Or exhibited or accredited 2 Or works of power 3 Or attesting miracles
4 Lit men without the Law; i.e. pagan

Heb. 9
26 Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been manifested to put away sin 1by the sacrifice of Himself.
1 Or by His sacrifice

The 1 Peter verse, in and of itself, is enough to corroborate the KJ's presentation of the text. It agrees in toto with the concept of the "slaying" being from the foundation of the world...whether or not the writing in the book was also.
Acts also indicates that the cross (and thus the slaying) was foreordained (clearly from before Creation).
Hebrews 9 indicates by implication that the suffering was "effectual" and "effected" from the foundation of the world in a spiritual sense (the only sense in which any of this is true), even though the "event" itself was manifested in its due season.
But these verses aren't all...though they do confirm the doctrinal validity of the KJ readings...and the Greek. Another verse from Hebrews ices this perspective perfectly:
Heb. 4
3 For we who have believed enter that rest, just as He has said,
“As I swore in My wrath,
They shall not enter My rest,”
although His works were finished from the foundation of the world.
New American Standard Bible : 1995 update. 1995 (Heb 4:3).
I would venture that all participants on this forum recognize the Cross as one of His most important works. Ergo, He (the Lamb) was slain from the foundation of the world/earth.
To my way of thinking, the proximity, validity, and doctrinal certainty that effuses from the KJ versions of this verse are so clear and overwhelming, that only something like "editorial pride" can account for the decision to "paint a mustache on the Mona Lisa" in the way that the modern versions have done here. It takes something very much like hhutspah to feel comfortable to make a change that requires a stretch across four chapters when a perfectly true and right option literally lies right beside.
The reason I even bothered to post this here is that the Lexham text has concurred with these other modern versions. I thought that someone might like to give a shot at explaining the reasoning for this wholly unnecessary change.
