The ESV includes the verse in the footnote. However, there is a deeper issue here with the translation of the KJV as a whole.
If you take, for example, John 3:16, there are translation errors in that particular verse--and some have taken the "whosoever believeth..." to mean it is primarily the will of man that makes the difference in salvation.
In reality, the verse, in the instance of the above example, says "all the ones believing." It makes no statement as to "whosoever" and, when properly translated, neither supports nor thwarts either the Arminian or Calvinist arguments.
As it is in the KJV, it seems to support the Arminian arguments, but the support is based on a faulty translation.
One of the great things about the modern translations, no matter which textual tradition they stem from, is that we now have slightly over 400 years more research into language (Koine Greek, to be specific, in this case) and textual research.
It still frustrates me that my ESV doesn't rightly translate John 3:16. The HCSB does and the ISV does. Perhaps so many translators leave the more beloved verses alone, even if they shouldn't. That too is error, but that's another discussion.
Blessings,
The Archangel

Nope. It sure sounds like "whosoever believes". Now, I am not going to get into a deep battle with you, seeing that you have studied the languages, whereas I haven't. By doing so, it would be like me bringing a seal to a polar bear fight......:laugh:
