The following verses are omitted from the ESV Bible in their entirety but are found in the Textus Receptus Greek New Testament, the text which underlies the New Testament of Reformation-era translations:
Matthew 17.21, 18.11, 23.14
Mark 7.16, 9.44, 9.46, 11.26, 15.28
Luke 17.36, 23.17
John 5.4
Acts 8.37, 15.34, 28.29
Romans 16.24
1 John 5.7 (the famous Trinitarian reading known as the Johannine Comma is omitted
without any footnote to explain its omission)
This is taken from
http://trinitarianbiblesociety.org.au/qr/QR563.pdf. Which I got in response to an earlier post.
I am in a quest to find out more about the ESV. I was always a user of the NASB. I am seeing if it is worth changing over.
