Many old, handwritten copies of New Testament writings, called manuscripts, survive and are in various places around the world.   Many are in "koine" Greek, a language spoken by ordinary people in Jesus' time.  They're not all the same.  Bible versions used in our day are not the same.  One reason is because editors choose to use different manuscripts as a basis for their Bible versions.  Using the links below, compare the King James Version (KJV) to the New American Standard Version (NASV).  Look at the words in red and compare.  The differences (or, variants) trace back to the manuscripts.  The red words agree with the manuscripts noted in parentheses at the end of the verse.  The major Greek manuscripts used here are called Aleph, A, B, and Byz.  Click Here to read about the manuscripts.
