Someone asked about why some of us like ESV over other Bibles. In Seminary, in Hebrew, we compared the various versions to the actual Hebrew. It only took a few weeks of translating to realize the ESV was closest to the original language. That is verb tenses, word order, and actual word usage. I have done a lot of translating of the Greek, and the same thing applies. I have an ESV study, and it has very good notes, which point out the variations, esp. when the words are not in the earliest manuscripts.
The problem with the Majority Texts or the Byzantine, is the only reason they are in the majority, is because the Greeks still spoke Greek, so they continued to reproduce the largest amount of manuscripts in that language, whereas other cultures translated into their languages. However, the later Greeks also liked to "embellish" the earlier texts, and that is why the later manuscripts have so many transcriptional errors. The KJV used those later manuscripts, which just have too many mistakes to be of value. More modern versions go back to the earlier texts, and translate them, instead of the later embellished Byzantine texts. I read from Nestle Aland, which puts all the variations and codes them to the particular manuscripts. That way I get the whole picture of where the variations crept in. Even so, I think most modern Bibles truly deliver the gospel. ESV can be very stilted. It does not follow the grammar as precisely as KJV, which is why so many people think KJV is poetic. It is actually because both Greek and to a lesser extent Hebrew have radically different word order than modern English. KJV often seems like a pretty turn of phrase, when it is in fact just following the original word order. No poetry there!
I am not against KJV, I memorized many verses in Sunday School when I was a young child, and those verses did not return void - I remembered them, and God saved me. In fact, it was nice to have consistence in memory verses. I think the modern versions have driven people away from memorizing, which to me is hiding God's Word in your heart. However, I still prefer to read a translation I know translates the original languages better than any other version. So that is ESV, after so much translating and comparing, I am pretty much convinced that it does the best job!
